1. Nucleon - Nucleon Interaction 

Abstract: Various contributions to nucleon-nucleon interaction in the singlet and triplet channels are studied with the help of a non-relativistic quark model (NRQM). The model Hamiltonian includes One - Gluon Exchange, Instanton Induced Interaction, and One - Pion Exchange.  The calculations were performed in the SU(2) NRQM using the Resonating Group Method.

3. Resonating Group Method - Overview and Applications

Abstract: Resonating Group Method is a technique used to study many body systems. Since its formulation in 1937, RGM has been state-of-the-art in studies of clustering in the light nuclei. It has also been used in studying condensed matter systems. In this talk, I plan to discuss the formal aspects of RGM and its applications to nuclear physics.

4. Low Energy Lepton-Proton Scattering - An EFT Approach.

Abstract: The structure of hadrons is an important problem that has far-reaching consequences. The lepton-proton scattering experiments are aimed at studying the structure of the protons. But, the experiments are less accurate in the low energy regime because of the difficulties involving the soft bremsstrahlung photons. This leads to a poor understanding of the low energy structure of hadrons. 

    HBChPT is the systematic expansion of the chirally invariant Lagrangian in the low energy regime with baryons as fundamental degrees of freedom. Thus, HBChPT forms a convenient tool to study the lepton-proton scattering process. In this talk, I will discuss our efforts to study low energy lepton-proton scattering using HBChPT.
