Constraints on the masses of fourth generation quarks

S. Hosseini, M. Mohammadi Najafabadi, A. Moshaii +2

We study the one-loop contribution of the down-type quark of the standard model-like fourth generation (b') on the top quark electric dipole moment. Using the known limits on the t…

NNLO QCD contributions to the flavor non-singlet sector of $F_{2} (x, Q^{2})$

Ali N. Khorramian, S. Atashbar Tehrani

We present the results of our QCD analysis for nonsinglet unpolarized quark distributions and structure function $F_{2} (x, Q^{2})$ . New parameterizations are derived for the nonsinglet…

The Jacobi Polynomials QCD analysis for the polarized structure function

S. Atashbar Tehrani, Ali N. Khorramian

We present the results of our QCD analysis for polarized quark distribution and structure function $x g_{1} (x, Q^{2})$ . We use very recently experimental data to parameterize our model.…

Spectator model in D meson Decays

Mehrdad Ghominejad, Hossein Mehraban

In this research we describe effective Hamiltonian theory and apply this theory to the calculation of current-current $Q_{12}$ and QCD penguin $Q_{3...6}$ decay rates We calculate…
