Motivated by the recent LHC data on the lepton-flavor violating (LFV) decays h (12) and B-s,B-d (12), we study the Higgs-mediated flavor-changing neutral current (FCNC) interactions in the effective field theory (EFT) approach without and with the minimal flavor violation (MFV) hypothesis, and concentrate on the later. After considering the B and K physics data, the various LFV processes, and the LHC Higgs data, severe constraints on the Higgs FCNC couplings are derived, which are dominated by the LHC Higgs data, the Bs-Bs mixing, and the e decay. In the general case and the MFV framework, allowed ranges of various observables are obtained, such as B(B-s (12)), B(h (12)), B(h q(1)q(2)), and the branching ratio of e conversion in Al. Future prospects of searching for the Higgs FCNC interactions at the low-energy experiments and the LHC are discussed.
