Charged-Higgs-boson effects in the B→Dτντ differential decay distribution
- 1. Institut fuer Theoretische Teilchenphysik, Karlsruhe Institute of Technology, 76128 Karlsruhe (Germany)
Description
We show that the decay mode B→Dτντ is competitive with and complementary to B→τντ in the search for charged-Higgs effects. Updating the relevant form factors, we find that the differential distribution in the decay chain B→Dνττ-[→π-ντ] excellently discriminates between standard model and charged-Higgs contributions. By measuring the D and π- energies and the angle between the D and π- three-momenta, one can determine the effective charged-Higgs coupling including a possible CP-violating phase.
