چکیده
For an Abelian extended Supergravity model, we investigate some important low energy parameters: tan β, Z − Z ′ mixing angle, lightest CP-even Higgs mass bound, Z ′ mass, and effective μ parameter. By integrating the RGE’s from string scale down to the weak scale we constuct the scalar potential, and analyze the quantities above at the treeand one-loop levels by including the contributions of top squarks and top quark in the effective potential.

Using the experimental result on b → sγ and theoretical result on b → sg, a four -generation SM is analysed to constrain the rephasinginvariant combinations of the CKM matrix and masses of the fourth generation quarks.

The radiative Bc → τ ν̄τγ decay is analyzed in the standard model. The branching ratio of this decay is calculated and the contributions of the Bremstrahlung and structure dependent parts are compared. It is shown that this decay can be detected at LHC.

Theoretical predictions for inclusive semileptonic B decay rates are rewritten in terms of the Υ(1S) meson mass instead of the b quark mass, using a modified perturbation expansion. This method gives theoretically consistent and phenomenologically useful results. Perturbation theory is well behaved, and the largest theoretical error in the predictions coming from the uncertainty in the quark ma...

We show that although there is no infrared divergence in exclusive P-wave quarkonium decays, the colour octet contribution is no less important than in the inclusive decay. Results from more proper calculations with only colour singlet contribution are not sufficient to account for the measured partial decay widths and so the next higher Fock state must be included. Using the χJ decay into N ¯ ...

We consider one-loop quantum corrections to soliton energies and central charges in the supersymmetric φ4 and sine-Gordon models in 1+1 dimensions. In both models, we unambiguously calculate the correction to the energy in a simple renormalization scheme and obtain ∆H = − 2π , in agreement with previous results. Furthermore, we show that there is an identical correction to the central charge, s...
