The forward η mesons production has been observed by the Large Hadron Collider forward (LHCf) experiment in proton-proton collision at s = 13 TeV. This paper presents the measurement of the inclusive production rate of η in pT < 1.1 GeV/c, expressed as a function of the Feynman-x variable. These results are compared with the predictions of several hadronic interaction models commonly used for the modelling of the air showers produced by ultra-high energy cosmic rays. This is both the first measurement of η mesons from LHCf and the first time a particle containing strange quarks has been observed in the forward region for high-energy collisions. These results will provide a powerful constraint on hadronic interaction models for the purpose of improving the understanding of the processes underlying the air showers produced in the Earth’s atmosphere by ultra-energetic cosmic rays.

We report the first measurement of the atmospheric neutrino-oxygen neutral-current quasielastic (NCQE) cross section in the gadolinium-loaded Super-Kamiokande (SK) water Cherenkov detector. In June 2020, SK began a new experimental phase, named SK-Gd, by loading 0.011% by mass of gadolinium into the ultrapure water of the SK detector. The introduction of gadolinium to ultrapure water has the effect of improving the neutron-tagging efficiency. Using a 552.2 day dataset from August 2020 to June 2022, we measure the NCQE cross section to be 0.74±0.22(stat)-0.15+0.85(syst)×10-38 cm2/oxygen in the energy range from 160 MeV to 10 GeV, which is consistent with the atmospheric neutrino-flux-averaged theoretical NCQE cross section and the measurement in the SK pure-water phase within the uncertainties. Furthermore, we compare the models of the nucleon-nucleus interactions in water and find that the binary cascade model and the Liège intranuclear cascade model provide a somewhat better fit to the observed data than the Bertini cascade model. Since the atmospheric neutrino-oxygen NCQE reactions are one of the main backgrounds in the search for diffuse supernova neutrino background (DSNB), these new results will contribute to future studies - and the potential discovery - of the DSNB in SK.

Transverse single-spin asymmetries AN of forward neutrons at pseudorapidities larger than 6 had only been studied in the transverse momentum range of pT<0.4 GeV/c. The RHICf Collaboration has extended the previous measurements up to 1.0 GeV/c in polarized p+p collisions at s=510 GeV, using an electromagnetic calorimeter installed in the zero-degree area of the STAR detector at the Relativistic Heavy Ion Collider. The resulting AN values increase in magnitude with pT in the high longitudinal momentum fraction xF range, but they reach a plateau at lower pT for lower xF values. For low transverse momenta, the AN's show little xF dependence and level off from intermediate values. For higher transverse momenta, the AN's also show a tendency to reach a plateau at increased magnitudes. The results are consistent with previous measurements at lower collision energies, suggesting no s dependence of the neutron asymmetries. A theoretical model based on the interference of π and a1 exchange between two protons could partially reproduce the current results; however, an additional mechanism is necessary to describe the neutron AN's over the whole kinematic region measured.

We report the first search result for the flux of astrophysical electron antineutrinos for energies(10)MeV in the gadolinium-loaded Super-Kamiokande (SK) detector. In 2020 June, gadolinium was introduced to the ultrapure water of the SK detector in order to detect neutrons more efficiently. In this new experimental phase, SK-Gd, we can search for electron antineutrinos via inverse beta decay with efficient background rejection thanks to the high efficiency of the neutron tagging technique. In this paper, we report the result for the initial stage of SK-Gd, during 2020 August 26, and 2022 June 1 with a 22.5 × 552 kton · day exposure at 0.01% Gd mass concentration. No significant excess over the expected background in the observed events is found for the neutrino energies below 31.3 MeV. Thus, the flux upper limits are placed at the 90% confidence level. The limits and sensitivities are already comparable with the previous SK result with pure water (22.5 × 2970 kton · day) owing to the enhanced neutron tagging. Operation with Gd increased to 0.03% started in 2022 June.

Cosmic-ray muons that enter the Super-Kamiokande detector cause hadronic showers due to spallation in water, producing neutrons and radioactive isotopes. These are a major background source for studies of MeV-scale neutrinos and searches for rare events. In 2020, gadolinium was introduced into the ultra-pure water in the Super-Kamiokande detector to improve the detection efficiency of neutrons. In this study, the cosmogenic neutron yield was measured using data acquired during the period after the gadolinium loading. The yield was found to be (2.76±0.02(stat)±0.19(syst))×10-4 μ-1 g-1 cm2 at an average muon energy 259 GeV at the Super-Kamiokande detector.

Search for solar electron anti-neutrinos due to spin-flavor precession in the Sun with Super-Kamiokande-IV 査読有り国際共著国際誌

Astroparticle Physics 139 巻 2022年6月

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：Astroparticle Physics

Due to a very low production rate of electron anti-neutrinos (ν̄e) via nuclear fusion in the Sun, a flux of solar ν̄e is unexpected. An appearance of ν̄e in solar neutrino flux opens a new window for the new physics beyond the standard model. In particular, a spin-flavor precession process is expected to convert an electron neutrino into an electron anti-neutrino (νe→ν̄e) when neutrino has a finite magnetic moment. In this work, we have searched for solar ν̄e in the Super-Kamiokande experiment, using neutron tagging to identify their inverse beta decay signature. We identified 78 ν̄e candidates for neutrino energies of 9.3 to 17.3 MeV in 2970.1 live days with a fiducial volume of 22.5 kiloton water (183.0 kton⋅year exposure). The energy spectrum has been consistent with background predictions and we thus derived a 90% confidence level upper limit of 4.7×10−4 on the νe→ν̄e conversion probability in the Sun. We used this result to evaluate the sensitivity of future experiments, notably the Super-Kamiokande Gadolinium (SK-Gd) upgrade.

An air shower simulation package COSMOS was born in 1970's and has been continuously developed. A recent major update enables particle tracking not only in the atmosphere but also in arbitrary gas, liquid and solid materials by combining with the EPICS detector simulation package. This paper describes the properties of this extended version of COSMOS, namely COSMOS X. Combination of gas, liquid and solid materials in spherical shells with a common center can be defined as environment. Users can also arbitrary define the electric and magnetic fields. These features allow shower simulations even in the soil, concrete, sea and ice. Also simulations at the Sun and the Mars are possible applications. Flexible input/output control since the previous versions of COSMOS, a set of user hook functions, is also available. In the predefined user functions, information of each particle in transportation can be easily accessed and users can extract information from them. General introduction to COSMOS and new functions of COSMOS X together with some interesting application cases will be presented in this paper.

The LHCf experiment, situated at the LHC accelerator, is composed of two independent detectors located at 140 metres from the ATLAS interaction point (IP1) on opposite sides along the beam axis. LHCf covers the pseudorapidity region above 8.4, with the capability to measure zero-degree neutral particles. The physics motivation of the experiment is to test the hadronic interaction models commonly used in ground-based cosmic rays experiments to simulate air-showers induced by ultra-high-energy cosmic rays (UHECR) in the Earth atmosphere. The data from accelerator experiments are very important for the tuning of these phenomenological models in order to reduce the systematic uncertainty of UHECR measurements. A precise measurement of the π0s produced in the very-forward region in high energy collisions provides the possibility to study the electromagnetic component of secondary particles produced in the first interaction of a UHECR with the atmosphere. In this contribution the preliminary results from the π0 analysis of the data acquired in proton-proton collisions at √s = 13 TeV will be presented. The Feynman-x and transverse momentum spectra obtained with the two detectors will be compared to show the consistency of the results.

The Relativistic Heavy Ion Collider forward (RHICf) experiment aims at understanding the high-energy hadronic interaction by measuring the cross sections of very forward neutral particles in proton-proton collisions at √s = 510 GeV. For the analysis of the photon measurement, the trigger efficiency and the particle identification performance are studied by using the Monte Carlo simulation data and the experimental data. In the RHICf operation, two kinds of trigger modes (Shower, HighEM) were implemented. The trigger efficiency of the Shower trigger is 100% for photons with the energies more than 20 GeV. The HighEM trigger is designed to detect high energy photons effectively, and the trigger efficiency of the HighEM trigger is 90% for photons with the energies more than 130 GeV. The correction factor for the photon identification is calculated by using the efficiency and purity. It is found that this correction does not make a sizeable effect on the shape of the energy spectrum because the energy dependency of the factor is small.

The LHCf experiment, at the Large Hadron Collider (LHC), consists of two small independent calorimeters placed 140 metres away, on opposite sides of the ATLAS interaction point (IP1). LHCf has the capability to measure zero-degree neutral particles, covering the pseudorapidity region above 8.4. By measuring the very-forward particle production rates at the highest energy possible at an accelerator, LHCf aims to improve our understanding of hadronic interactions in air-showers induced by ultra-high-energy cosmic rays in the atmosphere. This contribution will highlight recent results from Run II measurements with p-p collisions at 13 TeV. At first, the advantages of an ATLAS-LHCf combined analysis are discussed and a preliminary energy spectrum of very-forward photons produced in diffractive collisions as tagged by ATLAS is shown. The neutron energy spectrum measurements, for several pseudorapidity regions, are presented and compared with the predictions of various hadronic interaction models. From these measurements the average inelasticity of the collisions, which strongly affects the development of an air-shower, has also been extracted. Finally, the preliminary p0 Feynman-x and transverse momentum spectra, which affect the development of the electromagnetic component of an air-shower, are shown.

The LHC-forward (LHCf) experiment has measured the very forward neutral particle production cross section in proton-proton and proton-lead collisions at the LHC up to √s = 13 TeV and √sN N = 8.16 TeV, respectively. The experiment employs two independent detectors placed on opposite sides along the beam line approximately 140 meters away from the interaction point of the ATLAS experiment (IP1). The detectors are able to measure neutral particles with pseudorapidity greater than 8.4, up to zero-degree. These measurements are extremely useful for the calibration of the hadronic interaction models used to simulate the atmospheric showers of secondary particles induced from an high energy cosmic ray. Decreasing the uncertainty between different models it is possible to improve the precision of the high energy cosmic rays measurements. In this contribution the LHCf physics motivation for the Run III of LHC are discussed. The beam parameters and the expected operation time needed for our minimum physics program are described for both p-p run at 14 TeV and p-O run at 9.9 TeV. Finally, a brief summary of the ongoing upgrade on the Arm2 detector is given.

The LHCf experiment is designed to provide precise measurements of the production spectra relative to neutral particles produced in the very forward region by high energy proton-proton and proton-ion collisions. This information is necessary in order to test and tune hadronic interaction models used by ground-based cosmic rays experiments. In order to reach this goal, LHCf makes use of two small sampling calorimeters installed in the LHC tunnel at ±140 m from IP1, both able to detect neutral particles having pseudo-rapidity η > 8.4. In LHC Run II, LHCf acquired data relative to p-p collisions at √s = 13 TeV and p-Pb collisions at √sNN = 8.1 TeV. In this paper, we discuss the results obtained from p-p collisions at √s = 13 TeV, focusing in particular on photon and neutron production, the two analyses already published by the collaboration.

The main aim of the LHCf experiment is to provide precise measurements of the production spectra relative to neutral particles produced in the very forward region by high energy protonproton and proton-ion collisions. This information is necessary in order to test and tune hadronic interaction models used by ground-based cosmic rays experiments. In order to reach this goal, LHCf makes use of two small sampling calorimeters installed in the LHC tunnel at ±140 m from IP1, able to detect neutral particles having pseudo-rapidity η > 8:4. After the operations relative to p-p collisions at √s = 13 TeV, the collaboration focused the activity on the study of forward photons and neutrons production at this energy. In this paper, we discuss the recent results relative to the photons analysis, regarding, in particular, the inclusive production cross section, the role of diffractive and non-diffractive processes in forward photons production (investigated thanks to the LHCf-ATLAS joint analysis) and the forward differential energy flow.

The energy spectrum of forward photons measured by the RHICf experiment in vs = 510 GeV proton-proton collisions 国際共著国際誌

The Relativistic Heavy Ion Collider forward (RHICf) experiment aims at understanding the high-energy hadronic interaction by measuring the cross sections of very forward neutral particles in proton-proton collisions at vs = 510 GeV. For the analysis of the photon measurement, the trigger efficiency and the particle identification performance are studied by using the Monte Carlo simulation data and the experimental data. In the RHICf operation, two kinds of trigger modes (Shower, HighEM) were implemented. The trigger efficiency of the Shower trigger is 100% for photons with the energies more than 20 GeV. The HighEM trigger is designed to detect high energy photons effectively, and the trigger efficiency of the HighEM trigger is 90% for photons with the energies more than 130 GeV. The correction factor for the photon identification is calculated by using the efficiency and purity. It is found that this correction does not make a sizeable effect on the shape of the energy spectrum because the energy dependency of the factor is small.

The Relativistic Heavy Ion Collider forward experiment is ready to take data in the RHIC Run2017 √ s = 510 GeV p-p collisions using the LHCf Arm1 detector. New accelerator data are valuable to verify the Feynman scaling of FX1 production and to study the evolution of the break of scaling in neutron production. Using the transversely polarized proton beam, asymmetric production of forward neutrons is precisely measured. That is useful to understand the fundamental meson exchange in the proton-proton collisions.
