Monte Carlo studies for parameterization of B-mixing with dilepton events Song, Zhongzhi

Abstract

In this thesis, we report on a Monte Carlo (MC) study of the parameterization of probability distribution functions (PDFs) for neutral B mixing using dilepton events. T(45) decays are generated and those with at least 2 leptons in final state are used in this study. By choosing appropriate functions, a parameterization of the B meson decay time difference Δt is obtained by studying the B lifetime and the neutral B mixing frequency dependence of the dilepton events using an event re-weighting technique. Our results, combined with Monte Carlo studies of detector resolutions, can be used to obtain more precise measurements of the B mixing frequency and B lifetimes from experimental data.
