Single production of the gauge boson W via polarized e − γ collisions in the littlest Higgs model
Abstract
In the framework of the littlest Higgs(
LH
) model, we study single production of the standard model(
SM
) 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(

)
might be observed only for the scale parameter
f≤1.5TeV
and the mixing parameter
