Corrections to Landau Fermi-liquid fixed-point approximation in nonlinear bosonized theory: Application to $g_A^L$ in nuclei

Long-Qi Shao, Mannque Rho

We calculated in nonlinear bosonized theory $1/\bar{N}$ corrections to the Landau Fermi-liquid fixed-point (FLFP) axial-vector coupling constant in nuclear matter $g_A^L\approx 1$…
