All theoretical calculations are carried out without any adjustable parameter. We also show that the present results satisfy the Callan-Treiman low-energy theorem as well as the Ademollo-Gatto theorem. It turns out that the effects of flavor SU(3) symmetry breaking are essential in reproducing the kaon semileptonic form factors. The present results are in a good agreement with experiments, and are compatible with other model calculations.", "revisions": [ { "version": "v2", "updated": "2007-05-28T01:31:34.000Z" } ], "analyses": { "subjects": [ "14.40.Ag", "12.38.Lg" ], "keywords": [ "nonlocal chiral quark model", "kaon semileptonic decay", "kaon semileptonic form factors", "flavor su", "callan-treiman low-energy theorem" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 750809, "adsabs": "2007arXiv0705.2493N" } } }
