 +   <​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.
