Description

The present tensions between theory predictions and measurements in
semileptonic decays of bottom hadrons have sparked widespread interest
as possible indicators of Physics beyond the Standard Model. At the same
time, these tensions motivate thorough checks of the Standard Model
predictions, in terms of both methods and inputs. In this presentation I will
discuss recent and ongoing analyses of the hadronic matrix elements
emerging in b -> c tau^-\bar \nu transitions, and their impact on the
SM predictions of the lepton-flavour universality ratios R(D^(*)) and on
the determination of the CKM matrix element |V_cb|.
