Abstract：

The lightest new gauge boson B_Hwith mass of hundreds GeV is predicted in the littlest Higgs model. B_Hshould be accessible in the planned ILC and the observation of such particle can strongly support the littlest Higgs model. The realization of γγ and e^－γ collisions would open a wider window to probe B_H. In this paper, we study the new gauge boson B_Hproduction processes e－γ→e－γ
B_Hand e－γ→e－ZB_Hat the ILC. Our results show that the production cross section of the process e－γ→e－ZB_His less than 0.1fb in most parameter spaces allowed by the electroweak precision data while the cross section of the process e－γ→e－γB_Hcan be over one fb in the favorable parameter spaces. With the high luminosity, the enough typical signals could be produced via ee－γ→e－γB_H.
Because the final electron and photon beams can be easily identified and the signal can be easily distinguished from the backgrounds produced by Z and H decaying, e－γ→e－γB_His a promising process to probe B_H.
