Decay Constants of Pseudoscalar Mesons to Two Loops in Three-Flavor Partially Quenched ChPT

Bijnens, Johan LU and Lähde, Timo LU (2005) In Physical Review D (Particles, Fields, Gravitation and Cosmology) 71(9).
Abstract
This paper presents a first study of the decay constants of the charged, or flavor-off-diagonal, pseudoscalar mesons to two loops for three flavors of sea quarks, in Partially Quenched Chiral Perturbation Theory (PQChPT). Explicit analytical expressions up to order p<sup>6</sup> in the momentum expansion are given. The calculations have been performed within the supersymmetric formulation of PQChPT. We also present some numerical results to indicate the size of the corrections.
