Associated Production of Z_H and T in the Littlest Higgs Model at High Energy Linear e^-e^+ Collider

Abstract

In this work we study associated production of heavy Z boson and heavy top quark in the framework of Littlest Higgs model at e^-e^+ colliders considering parameter space allowed by the electroweak precision measurments. According to the free parameters of the model the possibility of detecting of new heavy particles at sqrt{s}=3 TeV and yearly integrated luminosity of L=500 fb^-1 are discussed. We find that in a narrow range of the parameter space, s/s'=0.8/0.6,0.7, 0.4 <= x_L <= 0.6 and f <~1060 GeV, a statical significance of 5 sigma can be achieved. We also discuss constraints on masses of heavy top quark and heavy Z boson together with the mixing parameters s and x_L at sqrt{s}=3000 GeV.
