Rare Higgs three body decay induced by top-Higgs FCNC coupling in the littlest Higgs Model with T-parity

Abstract

Motivated by the search for flavor-changing neutral current (FCNC) top quark decays at the LHC, we calculate rare Higgs three body decay $H\to Wbc$ induced by top-Higgs FCNC coupling in the littlest Higgs model with T-parity(LHT). We find that the branching ratios of $H\to Wbc$ in the LHT model can reach $\mathcal{O}(10^{-7})$ in the allowed parameter space.
