Hadronic Physics and Symbolic Calculations

Lay Summary 

Investigation on the origin, evolution and structure of the fundamental constituents of matter requires both experimental and theoretical effort. Chiral Perturbation Theory has been tremendously successful in describing low-energy hadronic (nuclear) interactions in the non-perturbative regime of Quantum Chromodynamics. The main purpose of our theoretical research is to take advantage of the new symbolic computing methods and to bring subatomic physics computations to the next level by developing a computational model with a consistent power-counting scheme within relativistic Chiral Perturbation Theory. Our recently developed Computational Hadronic Model (CHM) incorporates the octet of baryons, pseudoscalar and vector mesons, and decuplet of resonances. Extension of CHM towards the model with consistent power-counting (addresses consistent convergence of perturbation expansion) is our ongoing task. We are currently applying our new model in the calculations of the electromagnetic nucleon form factors using all of the possible degrees of freedoms of the effective chiral theory of strong interactions.

Our Computational Hadronic Model can also be applied to the studies of the impact of the hadronic effects on the parity violating electron-proton scattering. These studies in fact are crucial in the searches of the New physics beyond the Standard Model using high precision parity-violating experiments. In the most general sense, we will develop and use the advanced symbolic computational methods to study various production, decay and scattering channels in nuclear physics with very high degree of precision.
