$SU(4{)}_L\times U(1{)}_X$ models with little Higgs

Abstract

We discuss the aspects of the fermions and gauge bosons in $SU(4{)}_L\times U(1{)}_X$ models with little Higgs. We introduce a set of fermions which ensures the cancellation of gauge anomaly, and explicitly show the cancellation of one-loop quadratic divergence to the Higgs mass from all fermion multiplets and all gauge bosons. We present the interactions of the standard model fermions with the physical gauge bosons. We also discuss some phenomenological implications of the model based on recent experimental results.
