Finite Volume at Two-loops in Chiral Perturbation Theory
arXiv:1411.6384 · doi:10.1007/JHEP01(2015)034
Abstract
We calculate the finite volume corrections to meson masses and decay constants in two and three flavour Chiral Perturbation Theory to two-loop order. The analytical results are compared with the existing result for the pion mass in two-flavour ChPT and the partial results for the other quantities. We present numerical results for all quantities.
