Research Abstract

In this research project, based on the framework of perturbative QCD we have investigated the physics in the Standard Model and its beyond in the energy-frontier which can be attained by the Large Hadron Collider (LHC) as well as by the future linear collider (ILC). In particular we have studied the heavy quark mass effects on the virtual photon structure functions and parton distributions inside the photon. We also obtained the mass effects of the squark and gluino in the photon structure in the supersymmetric QCD. We further studied the axial anomaly and the sum rule of polarized photon structure function.
