+ | <hidden TTP08-06 Charged-Higgs effects in a new B -> D tau nu differential decay distribution > We present a detailed analysis of charged-Higgs effects in the decay B -> D | ||

+ | tau nu. Updating the relevant formfactors, we find this decay mode competitive | ||

+ | with and complementary to B -> tau nu. The differential distribution in the | ||

+ | decay chain B -> D nu tau[-> pi nu] excellently discriminates between | ||

+ | Standard-Model and charged-Higgs contributions. By measuring the D and pi | ||

+ | energies and the angle between the D and pi tracks one can determine the | ||

+ | magnitude and phase of the effective charged-Higgs coupling g_S. | ||
