The Lagrangians in R-xi gauge of the left right twin Higgs model and the application to processes gg -> h and h -> gamma gamma

摘要

The left right Higgs (LRTH) model, which adds an extra set of the Higgs to the Standard Model (SM) Higgs spectrum by the left right discrete symmetry, is one of the phenomenological realization of the new physics models to solve the little hierarchy problem. In this paper, we will, in the R-xi gauge, give the complete Lagrangians in this new physics model and then apply them to the processes gg -> h and h -> gamma gamma.
