  • Physics Interests:

    -Parity Violation: My actual research work and interests are based around the Strange Quark contribution to the Nucleon Electro-Magnetic properties using Parity Violation experiment G0 at Jlab. Results are getting released and complete flavor separation to the lightest three quarks is done. I am also interested in the incoming High Precision Measurement Parity Violation experiments at JLab.

    -SIDIS: My other research interest is still related to the strange sea quarks, but this time via Semi-Inclusive Deep Inelastic Scattering (SIDIS) of electrons off polarized deuteron or proton targets. Hadron production in DIS is described by the absorption of a virtual photon by a point-like quark followed by the fragmentation of this quark into hadronic final states. The first process is characterized by the quark distribution functions and the second process is characterized by fragmentation functions. Measuring multiplicities for several hadron species (pions and kaons) allows the control of the fragmentation functions used in the extraction of the individual quark and antiquark contributions to the nucleon spin.

    -Few Body Short Range Correlations: PhD. thesis related work. This branch of research has a promising future at higher energies... Who knows what is my interest going to be in 10 years. So many things we do not know about! :)
