Abstract
We have investigated the inclusive production of charged kaons from B mesons in ϒ (4S) decays. We present our results (up to 800 MeV/c) of the measurement of the charged kaon momentum spectrum, using information from the specific ionization (dE/dx) particle identification (PID) device. We fit PID histograms with known samples of primary (pion, kaon, proton) and secondary (electron, muon) control shape histograms, using a χ2 minimization technique. We compare our findings with ARGUS and with MC and comment on the implications for b → s g from the analsis.
