Abstract

Copyright © Flavor Physics and CP Violation, FPCP 2019.All rights reserved.Radiative corrections to B → D`ν` decays can have an impact on predictions and measurements of the lepton universality ratios R(D+) and R(D0). These proceedings summarise a study on the comparison between recent calculations of soft-photon corrections on these ratios and the corrections simulated by the Photos package. Also the impact of Coulomb interactions, not simulated in Photos, is discussed. Using pseudo-experiments, the effect of high-energy photon emission is studied in an LHCb-like environment, showing a bias of up to 7% on measurements of R(D).
