Calculation of the axial-vector coupling constant 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 in two covariant versions of two-flavor baryon chiral perturbation theory.…
Chiral perturbation theory
Véronique Bernard, Ulf-G. Meißner
We give a brief introduction to chiral perturbation theory in its various settings. We discuss some applications of recent interest including chiral extrapolations for lattice gaug…
Radiative tritium beta-decay and the neutrino mass
S. Gardner, V. Bernard, U. -G. Meißner
The shape of the electron energy spectrum in 3H beta-decay permits a direct assay of the absolute scale of the neutrino mass; a highly accurate theoretical description of the elect…
The reaction at threshold in chiral perturbation theory
V. Bernard, N. Kaiser, Ulf-G. Meißner
In the framework of heavy baryon chiral perturbation theory, we give thIn the framework of heavy baryon chiral perturbation theory, we give the chiral expansion for the $πN \to ππN…
Chiral Prediction for the Scattering Length to Order
V. Bernard, N. Kaiser, Ulf-G. Meißner
We evaluate the S-wave pion--nucleon scattering length in the framework of heavy baryon chiral perturbation theory up--to--and--including terms of order . We show that…
Novel Pion Electroproduction Low-Energy Theorems
V. Bernard, N. Kaiser, Ulf-G. Meißner
We present novel low--energy theorems for the P--wave multipoles , , and for neutral pion electroproduction off protons. These…
