摘要：

We consider lepton flavor violating Higgs decay, specifically h -> mu tau, in a leptoquark model. We introduce two scalar leptoquarks with the SU(3)(c) x SU(2)(L) x U(1)(Y) quantum numbers, (3, 2, 7/6) and (3, 2, 1/6), which do not generate dimension-4 operators mediating proton decay. They can mix with each other by interactions with the standard model Higgs. The constraint from the charged lepton flavor violating process, tau(-) -> mu(-)gamma, is very strong when only one leptoquark contribution is considered. However, we demonstrate that significant cancellation is possible between the two leptoquark contributions. We show hat we can explain the CMS (ATLAS) excess in h -> mu tau. We also show that muon (g - 2) anomaly can also be accommodated.
