The Branching ratio R(b) in the littlest Higgs model
Jan, 2004Citations per year
Abstract:
In the context of the littlest Higgs(LH) model, we study the contributions of the new particles to the branching ratio Rb. We find that the contributions mainly dependent on the free parameters f, c′ and xL. The precision measurement value of Rb gives severe constraints on these free parameters.- 12.60.Cn
