Explicit analytical expressions up to ${\\cal O}(p^6)$ in the momentum expansion are given. The calculations have been performed within the supersymmetric formulation of PQ$\\chi$PT. We also present some numerical results to indicate the size of the corrections.", "revisions": [ { "version": "v1", "updated": "2005-01-18T15:03:17.000Z" } ], "analyses": { "subjects": [ "12.38.Gc", "11.30.Rd", "12.39.Fe" ], "keywords": [ "decay constants", "pseudoscalar mesons", "three-flavor", "partially quenched chiral perturbation theory", "sea quarks" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
