Description
The observed discrepancy between the experimental results and the
Standard Model prediction for the ratios of the branching fractions of the decays
B-> D(*) tau nu and B-> D(*) mu nu came as a surprise and lead to a discussion of
testing New Physics through these modes. We discuss the possibilities for observing
the New Physics effects by examining the q^2 and the angular distributions of the
decay products. In particular we find new observables that could be accessible
experimentally and that can be sensitive to the effects of physics beyond the
Standard Model and be useful for discriminating various new physics scenarios.
