Flavor Changing Top Quark Decay and Bottom-Strange Production in the Littlest Higgs Model with T-parity

Flavor changing effects on the processes t → cA, e^＋e^- → bs^-, e^＋e^- →bs^-h and pp → bs^- in the LHT model are investigated in this paper. We calculate the one-loop level contributions from the T-parity odd mirror fermions and gauge bosons. The results show that the top quark rare decay t --~ cA in the LHT model can be significantly enhanced relative to that in the SM. The bs^- production at linear colliders in the LHT model can enhance the SM cross section a lot and reach 0.1 fb in some parameter space allowed in the experiment. But the heavy gauge boson and mirror fermion loops have small contribution to the processes pp --~ 5~ and e＋e- →bs^-h. So the LHT effect on e^＋e^- → bs^- might be detected at future linear colliders, while it is too sma/l to be seen for the e^＋e^- →bs^-h and pp → bs^- processes at future linear colliders and LHC.
