Query: Probing the lightest new gauge boson $B_H$ in the littlest Higgs model
  via the processes $\gamma\gamma \to f\bar{f}B_H$ at the ILC   The neutral gauge boson $B_H$ with the mass of hundreds GeV, is the lightest
particle predicted by the littlest Higgs(LH) model, and such particle should be
the first signal of the LH model at the planed ILC if it exists indeed. In this
paper, we study some processes of the $B_H$ production associated with the
fermion pair at the ILC, i.e., $\gamma\gamma\to f\bar{f}B_{H}$. The studies
show that the most promising processes to detect $B_H$ among $\gamma\gamma\to
f\bar{f}B_{H}$ are $\gamma\gamma\to l'^+l'^-B_{H}(l'=e,\mu)$, and they can
produce the sufficient signals in most parameter space preferred by the
electroweak precision data at the ILC. On the other hand, the signal produced
via the certain $B_H$ decay modes is typical and such signal can be easily
identified from the SM background. Therefore, $B_H$, the lightest gauge boson
in the LH model would be detectable at the photon collider realized at the ILC.
