Efficiency of B meson identification with kaon tagging in the HERA-B spectrometer

Diploma thesis, University of Ljubljana


Abstract

For the CP violation measurement in the neutral B meson system as proposed in the HERA-B experiment a highly efficient pion and kaon separation method is needed. The high efficiency is important because of the B meson flavor tagging with the kaon charge. An extended maximum likelihood method used for identification of charged particles (mainly pi and K) in the ring imaging Cherenkov counter is described. The performance of the method as a function of several crucial counter parameters is discussed.
