A simple extension of the standard model(SM) with a μ-flavored vector-like lepton(VLL) doublet and a real singlet scalar can have an interesting implication to the h→μ^(+)μ^(-)decay while offering the simplest pos...
We study the lepton flavor violatingμ−→e-2γdecay induced by the mediation of heavy leptons,such as the excited and fourth generation leptons.Effects of these leptons inμ−→e-2γdecay are examined.It is found that ...
The lepton polarization asymmetry in the B → e^+e^- decay, when one of the leptons is polarized, is investigated by using the most general form of the effective Hamiltonian. We find allowed regions for the new scala...

The quark-lepton mass spectra in q-deformed quantum mechanics are investigated. The theoretical formula of the spectrum includes two new quantum numbers: the q-exciting number n describing generations and the scaling ...

Under thermodynamic equilibrium, the initial values of the quark-gluon system from relativistic nucleus-nucleus collisions are obtained. From these initial values we have studied the dilepton production on the basis o...

Based on a relativistic hydrodynamic model,the dilepton production in a baryon-rich quark-gluon fireball is studied.We Hnd that at invariant masses between 2mπ and 1 GeV,with increasing initial baryon density,a chara...
Generalized Boltzmann approximation of the phase-space distribution function of quarks in the quark phase and of pions in the hadron phase,adopted by previous authors,to a complete expression,the dilepton production i...
