Description

In this paper tree-level violation of weak isospin parameter, ρ in the frame of the littlest Higgs model is studied. The potentially large deviation from the standard model prediction for the ρ in terms of the littlest Higgs model parameters is calculated. The maximum value for p for f=1 TeV, c=0.05, c'=0.05 and υ'=1.5 GeV is ρ=1.2973 which means a large enhancement than the SM. (authors)
