Description

The semileptonic b-hadron decays with a heavy lepton are sensitive to new couplings like those generated by charged Higgses or Leptoquarks. The B-Factories and LHCb have previously performed various measurements of these decays, using different approaches and techniques. A global average of these measurements shows a discrepancy with the Standard Model expectations, which is above 3 standard deviations. A measurement of the combined ratios BF(B->D tau nu)/BF(B->D mu nu) and BF(B->D tau nu)/BF(B->Dmu nu) using 3/fb collected by LHCb in Run1, is presented.
