The study of the charged top - pion decay processes
نویسندگان
چکیده
In the framework of top-color assisted technicolor(TC2) theory, we study the four decay processes of charged top-pion, i.e., Π+t → tb, Π+t → cb, Π+t → Wγ, Π+t → WZ, the decay branching ratio of these modes are calculated. The results show that the main decay channels of charged top-pion are the tree level modes: Π+t → tb̄ and Π+t → cb̄. Light Π+t is easier to be detected than heavy one at future coliders. So, the study provides us some useful information to search for charged top-pion.

Top Decay in Topcolor-Assisted Technicolor
Conventional technicolor models with light charged technipions (π T ) lead to an unacceptably large contribution to t → π T b decay rate. Topcolor-assisted technicolor models also have additional PGBs called top-pions (π t ) which may contribute to this decay. We study the potentially dangerous mixing of charged top-pion and technipions in toy models of ‘natural’ topcolor-assisted technicolor. ...
متن کاملImpact of tau polarization on the study of the MSSM charged Higgs bosons in top quark decays at the ILC
The process of top quark pair production at the ILC with subsequent decays of one of the top quarks to a charged Higgs boson and b-quark is considered. The charged Higgs decays to tau leptons whose polarization is the opposite to those coming from W bosons. This difference is reflected in the energy distributions of the tau decay products in the top quark rest frame, which can be reconstructed ...
متن کاملProduction and decay of the neutral top-pion in high energy e+e− colliders
We study the production and decay of the neutral top-pion π0 t predicted by topcolor-assisted technicolor(TC2) theory. Our results show that, except the dominant decay modes bb̄, t̄c and gg, the π0 t can also decay into γγ and Zγ modes. It can be significantly produced at high energy e+e− collider(LC) experiments via the processes e+e− → π0 t γ and e+e− → Zπ0 t . We further calculate the producti...
متن کاملStudy of the single neutral top - pion production process at γγ collider
γγ → Π0t is the major production mechanism of neutral top-pion at the linear colliders. In this paper, we calculate the cross section of the process γγ → Π0t and discuss the potential to observe the neutral top-pion via its various decay modes at the planned ILC. The study show that, among the various neutral top-pion production processes at the linear colliders, the cross section of γγ → Π0t i...
متن کاملQuantum Interference Effects in the Detection Probability of Charged Leptons Produced in Charged Current Weak Interactions
The phases of quantum interference effects in charged lepton production by neutrinos (neutrino oscillations) following pion decay at rest and in flight, muon decay and nuclear β−decay at rest as well as for ‘muon oscillations’ following pion decay at rest and in flight are calculated. The same phase is found for neutrino and muon oscillations following pion decay at rest. The results found disa...
