Testing the littlest Higgs model with T parity in bottom quark pair production at high energy photon colliders
Abstract
We have calculated the cross section of the process e^{+}e^{}→γγ→b bmacr in the littlest Higgs model with T parity (LHT). We find that, for the favorable parameters, the total cross section σ(e^{+}e^{}→γγ→b bmacr ) is sensitive to the breaking scale f, mixing parameter x_{L}, the masses of the mirror quarks m_{Hi}, and the relative correction of the LHT model is a few percent to dozens of percent. The cross section is significantly larger than the corresponding results in the standard model and in the other typical new physics models. Therefore the prediction in the LHT model is quite different from the predictions in other new physics models and such a process is really interesting in searching for the signs of the LHT model.
