Semileptonic b->c transitions allow for a determination of the CKM element V_cb and test Lepton Flavour Universality (LFU). 

Recent Belle results have been analysed using different parametrisation of the form factors, with puzzling implications for Vcb.

What is going on? and what are the consequences for the semitauonic decays and LFU tests?
