First Observation of the Decay tau- -> phi K- nu_tau Reviewed

Belle collaboration

Physics Letters B Vol. 643 page： 5-10 2006.11

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

We present the first observation of tau lepton decays to hadronic final states with a phi-meson. This analysis is based on 401 fb^-1 of data accumulated at the Belle experiment. The branching fraction obtained is B(tau- -> phi K- nu) = (4.05 + 0.25 + 0.26) x 10^-5.

Nucl. Instrum. Meth. A Vol. 564 page： 204-211 2006.4

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

To examine the lifetime of a micro-channel plate photo-multiplier tube, we measured its basic performance, gain, quantum efficiency (QE), transit time spread and dark counts as a function of the integrated amount of irradiated photons up to 2.8x10^14 photons/cm^2, corresponding to a 14-year time duration under supposed super-KEKB experimental conditions. The effect of the ion-feedback protection layer was clearly detected and the deterioration of the photo-cathode functioning was examined in terms of the QE spectrum on the light wavelength.

*A 5ps TOF-counter with an MCP-PMT Reviewed

K.Inami, N.Kishimoto, Y.Enari, M.Nagamine and T.Ohshima

Nucl. Instr. and Meth. A Vol. 560 page： 303-308 2006.1

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

We measured the timing resolution of TOF counters by means of Cherenkov-light detection with a Micro-Channel Plate Photo-Multiplier Tube, and attained sigma=6.2 ps using 3 GeV/c pion-beams with a readout electronics of 4.1 ps resolution. The optimum radiator thickness was examined and the detectable number of photo-electrons was analyzed.
