Recent results and prospects on semileptonic b decays from LHCb

Semileptonic decays of the beauty hadrons provide a platform to study the fundamental Standard Model parameters and reveal the potential New Physics contributions. Semileptonic b decays take high branching fractions and clean theoretical inputs, resulting in more precise measurements to be expected. At LHCb the studies on semileptonic b decays come with challenges, including the significant background contributions from the missing nuetrino and partially reconstructed decays and the higher reliance on simulation. Therefore specialization analysis strategies are required for the studies of semileptonic b decays at LHCb.

In this presentation, recent studies on semileptonic b decays at LHCb will be reported, including the measurements of the fundamental quark mixing parameter V_cb, the measurements of  the semileptonic asymmetry in B⁰/B_s semileptonic decays, and studies of the lepton universality. Besides, the prospects of measuremnts of semileptonic b decays at LHCb in the future will be discussed.
