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.
