Sunset integrals with up to three mass scales in chiral perturbation theory: a comparative study of the Mellin-Barnes representation technique
Balasubramanian Ananthanarayan, Sumit Banik, Véronique Bernard +3
Sunset integrals are among the simplest of two-loop integrals that appear in perturbative quantum field theories and possess up to four distinct mass scales. By means of integratio…
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…
