We calculate the strong coupling constants gP P ∗π, where P ∗∗ (D∗∗, B∗∗) is the 1+ p-wave state, in the framework of the light cone QCD sum rules, and using these values of gP P ∗π, we compute the hadronic decay widths for D ∗∗ → D∗ π and B∗∗ → B∗ π. ∗Permanent address: Institute of Physics, Azerbaijanian Academy of Sciences, Baku, Azerbaijan

We study unparticle physics effects in Λb → Λ + missing energy decay with polarized Λb and Λ baryons. The sensitivity of the branching ratio of this decay and polarizations of Λb and Λ baryons on the scale dimension dU and effective cut–off parameter ΛU are discussed. e-mail: [email protected] permanent address:Institute of Physics,Baku,Azerbaijan e-mail: [email protected]

Using the most general form of the baryon current, nucleon form factors, induced by isovector and isoscalar axial–vector currents, are studied in the framework of light cone QCD sum rule approach. Comparison of our results on form factors with the existing results and lattice calculations are presented.

The transition form factors of Ds → f0lν, D → f0lν and Bu → f0lν decays are calculated in 3–point QCD sum rule method, assuming that f0 is a quark–antiquark state with a mixture of strange and light quarks. The branching ratios of these decays are calculated in terms of the mixing angle. e-mail: [email protected] permanent address:Institute of Physics,Baku,Azerbaijan e-mail: [email protected]

The transition form factors of the semileptonic decay Bs into scalar Ds0(2317) meson is calculated in the framework of 3–point QCD sum rule. The branching ratio is found to be ∼ 10−3 for the Bs → Ds0(2317)lν̄l (l = e, μ) decay, and ∼ 10−4 for the Bs → Ds0(2317)τ ν̄τ decay, respectively. e-mail: [email protected] permanent address:Institute of Physics,Baku,Azerbaijan e-mail: [email protected]

Layered semiconductors have become increasingly interesting due to their structural properties and potential applications in optoelectronics. Their quasi-two-dimensionality, optical and photoconductive properties, and other features attract investigators in an effort to acquire a better insight into the physics of these compounds. Layered ternary crystals TlInS2 and TlGaS2 are the anisotropic c...

Double–lepton polarization asymmetries in Λb → Λl+l− decay are calculated in universal extra dimension (UED) model. It is obtained that numerous double–lepton polarization asymmetries are very sensitive to the UED model and therefore can be very useful tool for establishing new physics predicted by the UED model.
