Nucleon's axial-vector form factor in the hard-wall AdS/QCD model

The axial-vector form factor of the nucleons is considered in the framework of hard-wall model of holographic QCD. A new interaction term between the bulk gauge and matter fields was included into the interaction Lagrangian. We obtain the axial-vector form factor of nucleons in the boundary QCD from the bulk action using AdS/CFT correspondence. The momentum square dependence of the axial-vector form factor is analysed numerically.

Lepton Asymmetries for the $B_s -> γl^+ l^- $ Decay in a Family Nonuniversal Z' Model

The exclusive $B_s -> γl^+ l^- $ decay is analyzed in the framework of a family nonuniversal Z' model by calculating the differential branching ratio, double lepton polarizations and forward-backward asymmetries. Our results are compared against those of the Standard Model. The predictions of this work are hoped to can be tested in the near future at LHCb.

Semileptonic Lambda(b)-->Lambda neutrino antineutrino decay in the Leptophobic Z-prime model

We study the exclusive flavor chancing neutral current process Lambda(b)-->Lambda neutrino antineutrino in the leptophobic Z-prime model, where charged leptons do not couple to the extra Z-prime boson. The branching ratio, as well as, the longitudinal,transversal and normal polarizations are calculated. It has been shown that all these physical observables are very sensitive to the existence of new physics beyond the standard model and their experimental measurements can give valuable information about it.
