Detailed Description

The class calculates the helicity amplitude of semi-tauonic B decays including new physics effects based on [M.

Tanaka and R. Watanabe PRD87,034028(2013)].

The class implements helicity amplitude of the B->D*taunu and B->Dtaunu decays including new physics effects described in [M. Tanaka and R. Watanabe Phys. Rev. D87, 034028 (2013)]. The five possible new physics contributions are included: V1=left handed vector type (SM like), V2=right handed vector type, S1=scalar type (S+P), S2=scalar type (S-P), T=tensor type.
