CERN LEP 가속기에서의 ALEPH 검출기를 통한 B^0_s 중간자 탐색
남지우,김동욱,노상률,최영일 성균관대학교 기초과학연구소 1997 論文集 Vol.48 No.-
We have searched for B^0_s meson using about 4.2 million hadronic Z^0 decays collected by the ALEPH detector at LEP from 1991 to 1995. The B^0_s decay modes include B^0_s → D^-_sπ^+, B^0_s → D^-_sπ+π^-π^+ (D^-_s a^+_1, D^-_s ρ^0π^+). There were eight events in the signal region with some background. Two clean B candidate events were found in the eight events. They are B^0_s →D^-_sπ^+, B^0_s →D^-_sρ^0π.

We investigated the properties of BELLE Time Of Flight(TOF) counter using the data taken in Jan 98 beam test at Pi2 beam line at KEK 12 GeV proton synchrotron. Charge distributions from readout PMT were analysed in comparison with dE/dx distributions predicted by GEANT full simulation. Experimental setup of the beam test is described, then procedures of data analysis, Monte Carlo simulation and analysis results are also described.
