Finite volume for three-flavour Partially Quenched Chiral Perturbation Theory through NNLO in the meson sector

Bijnens, Johan LU orcid and Rössler, Thomas LU (2015) In Journal of High Energy Physics
Abstract
We present a calculation of the finite volume corrections to meson masses and decay constants in three flavour Partially Quenched Chiral Perturbation Theory ( PQChPT) through two-loop order in the chiral expansion for the flavour-charged ( or off-diagonal) pseudoscalar mesons. The analytical results are obtained for three sea quark flavours with one, two or three different masses. We reproduce the known in finite volume results and the finite volume results in the unquenched case. The calculation has been performed using the supersymmetric formulation of PQChPT as well as with a quark flow technique. Partial analytical results can be found in the appendices. Some examples of cases relevant to lattice QCD are studied numerically. Numerical... (More)
