Effects of the Little Higgs Models on Single Top Production at the eγ Colliders

  • In the framework of the littlest Higgs(LH) model and the littlest Higgs model with T-parity(LHT), we investigate the single top production process eγ→νebt, and calculate the corrections of these two models to the cross section of this process. We find that in the reasonable parameter space, the correction terms for the tree-level Wtb couplings coming from the LHT model can generate significantly corrections to the cross section of this process, which might be detected in the future high energy linear e+e collider(ILC) experiments. However, the contributions of the new gauge boson W±H predicted by the LH model to this process are very small.

Abstract: In the framework of the littlest Higgs(LH) model and the littlest Higgs model with T-parity(LHT), we investigate the single top production process eγ→νebt, and calculate the corrections of these two models to the cross section of this process. We find that in the reasonable parameter space, the correction terms for the tree-level Wtb couplings coming from the LHT model can generate significantly corrections to the cross section of this process, which might be detected in the future high energy linear e+e collider(ILC) experiments. However, the contributions of the new gauge boson W±H predicted by the LH model to this process are very small.
