Research Activities

I started officially y research activities during my M.Sc. plan by submiting my thesis on "Simulation of Intermitency and multifractal in production of particle, using the branching model". During my Ph.D. Plane in Durham University of England and the one year Period after that when I was working there as a research assistance, three papers in Nucl. Phys. B were published which are mostly related to phenomenology aspects of perturbative part of QCD. Since I started my collaboration with IPM in october 2002, I was doing my research on obtaining unpolarized and polarized parton distributions and nucleon structure functions by using quark distributions. Other activity is to employ Complete Renormalization Group Improvemnt approach in analysing of $b\bar{b}$production in proton-antiproton collisions.

Present Research Project at IPM

1- Complete Renormalization Group Improvement analysis of $b\bar{b}$production in proton-antiproton collisions. 2- Nuclear Structure Function using Quark Distribution Function.
