Possibility of Detecting the top-Higgs at High Energy e+e Colliders

  • In the context of topcolor assisted technicolor(TC2) models,we calculate the contributions of the top Higgs h0t to e+e→c eν e and compare the results with that of h0t to the processes e+e→ Zh0t→Zc and e+e→γh0t→γc. We further discuss the signals of these process at high energy e+e collider (LC) experiments. We find that e+e→c eν e is very sensitive to h0t,which can be easily detected via this process in the future LC experiments with s=500—1500GeV,as long as its mass below the t threshold. The processes e+e→Zc and e+e→γc can also be used to detect h0t in the future LC experiments with s=500GeV.

Abstract: In the context of topcolor assisted technicolor(TC2) models,we calculate the contributions of the top Higgs h0t to e+e→c eν e and compare the results with that of h0t to the processes e+e→ Zh0t→Zc and e+e→γh0t→γc. We further discuss the signals of these process at high energy e+e collider (LC) experiments. We find that e+e→c eν e is very sensitive to h0t,which can be easily detected via this process in the future LC experiments with s=500—1500GeV,as long as its mass below the t threshold. The processes e+e→Zc and e+e→γc can also be used to detect h0t in the future LC experiments with s=500GeV.
