Possible Flavor Changing Signals of the Littlest Higgs Model on High-Energy Linear Collider

  • Due to the presence of extra top quark T in the little Higgs model, the CKM matrix is not unitary and the flavor changing neutral currents may exist at the tree level. We discuss the possibility of detecting the flavor changing signals of the Littlest Higgs(LH) model at the high-energy linear e+e collider (ILC) via the processes e+e→tc+tc and e+e→WWνeνe→(tc+tc) νeνe. We find that the resonance production cross section for the process e+e→tc+tc is significantly large, which can be detected in the future ILC experiment.

Abstract: Due to the presence of extra top quark T in the little Higgs model, the CKM matrix is not unitary and the flavor changing neutral currents may exist at the tree level. We discuss the possibility of detecting the flavor changing signals of the Littlest Higgs(LH) model at the high-energy linear e+e collider (ILC) via the processes e+e→tc+tc and e+e→WWνeνe→(tc+tc) νeνe. We find that the resonance production cross section for the process e+e→tc+tc is significantly large, which can be detected in the future ILC experiment.
