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 <sup>v</sup>s = 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.
