Calculation of the axial-vector coupling constant $g_{A}$ to two loops in covariant chiral perturbation theory

Véronique Bernard, Jambul Gegelia, Shayan Ghosh +1

We present a calculation of the leading two-loop corrections to the axial-vector coupling constant $g_{A}$ in two covariant versions of two-flavor baryon chiral perturbation theory.…
