Three-flavor partially quenched chiral perturbation theory at NNLO for meson masses and decay constants
(2006) In Physical Review D (Particles, Fields, Gravitation and Cosmology) 73(7: 074509).- Abstract
- We discuss partially quenched chiral perturbation theory (PQ chi PT) and possible fitting strategies to lattice QCD data at next-to-next-to-leading order (NNLO) in the mesonic sector. We also present a complete calculation of the masses of the charged pseudoscalar mesons, in the supersymmetric formulation of PQ chi PT. Explicit analytical results are given for up to three nondegenerate sea-quark flavors, along with the previously unpublished expression for the pseudoscalar meson decay constant for three nondegenerate sea-quark flavors. The numerical analysis in this paper demonstrates that the corrections at NNLO are sizable, as expected from earlier work.
