## Elementary Particle Physics

**Research Areas:**

- Structure function of hadrons and nuclei, EMC effect, Perturbative and nonperturbative quantum chromodynamics, Quark-gluon plasma, Gluon fusion contribution in Higgs boson cross section, Calculation of parton functions corresponding to transverse momentum and their roles in production of heavy mesons.
- Many particle systems in strong interaction and short range.
- Field theory and particle Physics in curved space time, Early universe, Dark energy, Dark matter.
- Topological effects in Particle Physics.
- The idea of holography (gauge/gravity duality) and its applications in the strongly coupled theories, most importantly, QCD and QGP (Quark-Gluon Plasma).
- Studying QCD vacuum by topological defects like monopoles and dyons and center vortices,QCD and lattice gauge theory, Using phenomenological models to study quark confinement and calculating the potential between quarks.
