Pionic contribution to relativistic Fermi Liquid parameters

摘要

We calculate pionic contribution to the relativistic Fermi Liquid parameters(RFLPs) using Chiral Effective Lagrangian. The RFLPs so determined are thenused to calculate chemical potential, exchange and nuclear symmetry energiesdue to $pi$$N$ interaction. We also evaluate two loop ring diagrams involving$sigma$, $omega$ and $pi$ meson exchanges and compare results with what oneobtains from the relativistic Fermi Liquid theory (RFLT).
