====== TTP08-06 Charged-Higgs effects in a new B -> D tau nu differential decay distribution ======
 
 
   <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.
