Dimuon CP Asymmetry in B Decays and Wjj Excess in Two Higgs Doublet Models

Abstract

We analyze the puzzle of the dimuon CP asymmetry in B_s decays in two Higgs doublet models. We show that the flavor changing neutral current (FCNC) induced by the Higgs coupling in a type III two Higgs doublet model provides a solution to the dimuon charge asymmetry puzzle by enhancing the absorbtive part of the mixing amplitude Γ_{12}^s. We investigate different experimental constraints and show that it is possible to enhance Γ_{12}^s in order to explain the dimuon asymmetry observed by D0. This enhancement requires large Higgs couplings to the first and second generations of quarks which may also explain the recent 3.2 σWjj excess observed by CDF.
