Description
We study constraints and implications of the recent LHCb measurement of Bs -> mu mu for tree-level Higgs-mediated flavor-changing neutral current (FCNC) interactions. Combined with experimental data on Bs mass difference , the h -> mu tau, and the h -> tau tau decay branching ratios from the LHC, we find that the Higgs FCNC couplings are severely constrained. Current data allow large CP violation in the h -> tau tau decay. Consequences of the Cheng-Sher ansatz for the Higgs Yukawa couplings are discussed.
