Single production of the gauge bosons W± via polarized e-γ collisions in the littlest Higgs model

In the framework of the littlest Higgs (LH) model, we study single production of the standard model gauge boson W_s^- and the heavy gauge boson W_H^- via polarized e^-γ collisions. We find that the corrections of the LH model to the cross section σ(W_s^-) might be observed only for the scale parameter f≤1.5TeV and the mixing parameter c^'≥0.4 in future high-energy linear e⁺e^- collider (LC) experiments with the center-of-mass energy s=500GeV and a yearly integrated luminosity L=100fb^-1. However, with a suitably chosen polarization of the initial electron and positron beams, the possible signals of the heavy gauge boson W_H^- can be easily detected via e^-γ collisions in future LC experiments with s=3TeV and L=500fb^-1.
