Single production of new gauge bosons from the littlest Higgs model at the $TeV$ energy $e^{-}\gamma$ colliders

Abstract

In the context of the littlest Higgs(LH) model, we study single production of the new gauge bosons $B_H$, $Z_H$ and $W_H^{\pm }$ via $e^{-}\gamma$ collisions and discuss the possibility of detecting these new particles in the $TeV$ energy $e^{+}{e}^{-}$ collider($LC$). We find that these new particles can not be detected via the $e^{-}\nu \nu$ signal in all of the parameter space preferred by the electroweak precision data. However, the heavy gauge bosons $B_H$ and $Z_H$ may be observed via the decay channel $B_H(Z_H)\to l^{+}{l}^{-}$ in wide range of the parameter space.
