Description
We present the measurement of the B -> D(*) tau nu decay,
which is sensitive at tree level to New Physics in the form
of a charged Higgs Boson.
The measured branching fraction is 3.4 sigma larger than
the SM predictions, and excludes the 2HDM of type 2 at 99.88%
confidence for all tan(beta)/mHiggs values. Additional studies of
the momentum transferred to the lepton system show that the result
can be accommodated by more general two-Higgs-Doublet models.
Searches for rare decays sensitive to New Physics, as
B -> K(*) nu anti-nu, are also reported.
