The process in the 2HDM with flavor changing neutral currents
We consider the process in the framework of
a two Higgs doublet model with flavor changing neutral currents (FCNC). Since
FCNC generates in turn flavor changing charged currents in the lepton sector,
this process appears at tree level mediated by a charged Higgs boson exchange.
From the experimental upper limit for this decay, we obtain the bound whererefers to
the mixing between the first and second lepton generations, and denotes the mass of the charged Higgs boson. This bound is independent on the
other free parameters of the model. In particular, for GeV we get Comment: 2 pages, no figure
