abstract

  • We analyze the puzzle of the dimuon CP asymmetry in B decays in two Higgs doublet models. We show that the flavor changing neutral current induced by the Higgs coupling in a general two Higgs doublet model provides a solution to the dimuon charge asymmetry puzzle by enhancing the absorptive part of the mixing amplitude 12s . We investigate different experimental constraints and show that it is possible to enhance 12s in order to explain the dimuon asymmetry observed by D0 collaboration. This enhancement requires large Higgs couplings to the first and second generations of quarks which may also explain the recent Wjj excess observed by CDF. 2012 SISSA.
