“…Several phenomenological work have been done in order to explain the discrepancies in R D , R D * , R l π , and R µ e K , see in particular Ref. [6,19,21,. Ratio of branching ratios such as R D , R D * , R l π , R π , and R µ e K are excellent observables to test for new physics (NP) mainly because of two reasons.…”

“…A prediction on the ratio of branching ratios R π of B → πτ ν to the corresponding B → π l ν decays has also been reported in Refs. [18][19][20][21][22]. Several phenomenological work have been done in order to explain the discrepancies in R D , R D * , R l π , and R µ e K , see in particular Ref.…”

B→πτν¯τdecay in the context of type II 2HDM

“…Similar predictions have been discussed in Refs. [7][8][9][10][11]. Recent progress in the understanding of the B → π form factor as well as the availability of first experimental results give a strong motivation to revisit this topic.…”

“…Possible contribution of a H + and other couplings in the 2HDM and MSSM [12,13], which would affect the branching fraction and the differential ratio of branching fractions, have been evaluated in Refs. [2] and [14][15][16][17].…”
