BLOR - A Monte Carlo generator for radiative corrections in exclusive semileptonic B-meson decays — •Florian Bernlochner and Heiko Lacker — Humboldt Universität zu Berlin
Over the last 10 years an increasing amount of data and better understanding of detector effects lead to very accurate measurements of the CKM matrix elements Vub and Vcb from semileptonic B-meson decay rates. In order to match today’s experimental precision a good understanding of QED correction effects is important: occurring virtual and real photons couple to all charged particles in the decay process, altering partial and total rates. We present the current progress of the theoretical calculation and simulation of NLO QED corrections for various exclusive semileptonic B-meson decay channels. In addition we compare our simulated corrections from our Monte Carlo generator BLOR with NLL algorithms.
