- The Process... in the 2HDM with Flavor Changing Neutral Currents Rodolfo A. Diaz R. Martínez Nicanor Poveda Física, Astronomía y Matemáticas We consider the process ¹ ! ºeeº¹ 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 j»¹e=mH+j · 3:8 £ 10¡3 GeV¡1, where »¹e refers to the mixing between the first and second lepton generations, and mH§ denotes the mass of the charged Higgs boson. This bound is independent on the other free parameters of the model. In particular, for mH§ ' 100 GeV we get j»e¹j . 0:38. 2003 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46413573038 es http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4 Vol.33
