HFAG P(χ ) = 55% R(D) Combining results for R(D ) from Belle, BaBar and LHCb gives a 3.9σ discrepancy with the Standard Model. Recent results on R(D William ) and Sutcliffe V ub October 7, 15 1 / 13
13 Conclusion Conclusion LHCb has peformed two measurements using semileptonic decays which were unepected from a hadron collider: V ub = (3.7±.3) 1 3. This measurement is 3.5σ below the inclusive measurement but agrees well with current eclusive average using B πlν decays. R(D ) =.336±.7(stat)±.3(syst) Together with measurements from the B factories this is an eciting hint of lepton flavour universality violation and hence new physics.
