Looking for possible new physics in $B\to D^{(\ast )}\tau {\nu }_{\tau }$ in light of recent data

Srimoy Bhattacharya, Soumitra Nandi, Sunando K. Patra

We study the decays $B\to D^{(\ast )}\tau {\nu }_{\tau }$ in light of the available data from BABAR, Belle and LHCb. We divide our analysis into two parts: in one part we fit the form-factors in t…
