Probing the littlest higgs model in e(-) e(+) -> W-H(+) (T)over-bar b process

Abstract

In this work associated production of heavy W boson, heavy top quark and bottom quark in the framework of Littlest Higgs Model at high energy e(-) e(+) colliders and decay widths of heavy particles are analyzed. Detecting possibility of these new heavy particles in Littlest Higgs Model depend on free parameters which are constrained by the electroweak precision measurements. Production cross section of heavy W boson, heavy top quark and bottom quark is calculated at root s = 3 TeV and yearly integrated luminosity of L = 500 fb(-1)Achieving a statistical significance of 50-restricts the model in a narrow region with s/s' = 0.8/0.6, 0.7, 0.35 <= x(L) <= 0.6 and f <= 1.06 TeV.
