Production of the new gauge boson BH via e collision in the littlest Higgs model

  • The lightest new gauge boson BH with mass of hundreds GeV is predicted in the littlest Higgs model. BH should be accessible in the planned ILC and the observation of such particle can strongly support the littlest Higgs model. The realization of γγ and eγ collisions would open a wider window to probe BH. In this paper, we study the new gauge boson BH production processes e-γ→e-γ
    BH and e-γ→e-ZBH at the ILC. Our results show that the production cross section of the process e-γ→e-ZBH is less than 0.1fb in most parameter spaces allowed by the electroweak precision data while the cross section of the process e-γ→e-γBH can be over one fb in the favorable parameter spaces. With the high luminosity, the enough typical signals could be produced via ee-γ→e-γBH.
    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-γBH is a promising process to probe BH.

Production of the new gauge boson BH via e collision in the littlest Higgs model

    Corresponding author: WANG Xue-Lei,

Abstract: 

The lightest new gauge boson BH with mass of hundreds GeV is predicted in the littlest Higgs model. BH should be accessible in the planned ILC and the observation of such particle can strongly support the littlest Higgs model. The realization of γγ and eγ collisions would open a wider window to probe BH. In this paper, we study the new gauge boson BH production processes e-γ→e-γ
BH and e-γ→e-ZBH at the ILC. Our results show that the production cross section of the process e-γ→e-ZBH is less than 0.1fb in most parameter spaces allowed by the electroweak precision data while the cross section of the process e-γ→e-γBH can be over one fb in the favorable parameter spaces. With the high luminosity, the enough typical signals could be produced via ee-γ→e-γBH.
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-γBH is a promising process to probe BH.
