| 摘 要： | 在左右双Higgs模型(LRTH)中,研究了单个顶夸克在大型强子-电子对撞机上通过e+b→veT和γb→W-T过程的产生.对于顶夸克主要的衰变模式T→+b→tbb,这两个过程会分别产生3b+l+ET和3b+2l+ET的末态信号.当电子能量Ee=500GeV,质子能量取Ep=7TeV时,发现产生截面在顶夸克质量小于600GeV时会达到几十fb.也对T→W+b的衰变模式进行了唯像分析.

| Abstract: | In the context of the left-right twin Higgs model,we study single production of the Tquark at the Large Hadron electron Collider(LHeC),which proceed via the processes e+b→eT and γb→W-T.For the main decay mode T→+b→tb,these two processes mainly transfers to the final states of 3b+l+ET and 3b+2l+ET,respectively.With the electron energy Ee=500 GeV and photon energy Ep=7 TeV,we find that the production rates can reach tens fb when the heavy Tquark mass smaller than 600 GeV.A simply phenomenological analysis is also given for the decay mode T→W+b. |
