In this publication electroweak next-to-leading order corrections to semileptonic B-meson decays into (pseudo)scalar final states are presented. To this end, these corrections of O(alpha G_F) have been calculated in the QED-enhanced phenomenological model, incorporating the bound-state mesons as its degrees of freedom, and matched to a similar calculation on the level of constituent partons in the full Standard Model. Consequently, the effects arising due to corrections of the partial decay widths on the extraction of the CKM matrix elements |V_cb| and |V_ub| are detailed. Further, the results of two independent Monte-Carlo implementations are presented: One is the dedicated, strict fixed-order generator BLOR, and the other is embedded into the generic Yennie-Frautschi-Suura-type resummation of Photons++, which is part of the multi-purpose event generator Sherpa. The resulting distributions are compared against the standard tool used in many experimental analyses, PHOTOS, showing improvements on the shapes of kinematic distributions of both the lepton and the final state meson.
