We investigate the vector-like fourth generation coming from Split-UED to the contribution of the Higgs physics. We calculate the cross section from one-loop induced $gg->H$ process, and the branching ratio from $H->gg$ and $H->\gamma \gamma$ processes. The work now is still in progress.

The ALICE experiment, one of the four LHC experiments at CERN, is about studying the physics of strongly interacting matter at extreme energy densities, where the formation of a new phase of matter, the quark-gluon plasma, is expected. Several petabytes of data are expected to be produced from the ALICE detector annually. There are more than 1000 ALICE scientists around the world who want to...

The B --> V T (V and T denote vector and tensor mesons respectively) decays, whose final-state particles can have transverse or longitudinal polarization, are investigated in perturbative QCD (pQCD) approach. Measurements have been made of B --> phi K_2^*, and it is found that f_T / f_L is small, whereas f_T / f_L ~ 1 for B --> omega K_2^* where f_T(f_L) is the fraction of transverse...

In the 3-3-1 model with right-handed neutrinos, small neutrino masses can be obtained by introducing a Higgs sextet. The neutrino mass is the result of a type II seesaw mechanism. In addition to the ordinary heavy right-handed neutrinos, there exits the scalar sextet coupled to leptons. We study the contributions of the right-handed neutrinos and the sextet to the lepton asymmetry.

The current measurements of CP asymmetries in B -> K pi decays are in disagreement with the predictions of the Standard Model. In order to solve this discrepancy, using the effective Hamiltonian approach, we investigate the right-handed current contributions to B -> K pi decay amplitudes including all possible low-energy operators in the nonmanifest left-right model. We find the allowed region...
