Using Weinberg's sum rules, we compute the decay constant $f_\\pi$ of the Goldstone modes and find agreement with previous derivations. Using Das's sum rule, we also estimate the contribution of electromagnetic interactions to the mass of the charged modes. Finally, we comment on low temperature corrections to the effective field theory describing the Goldstone bosons.", "revisions": [ { "version": "v2", "updated": "2000-10-27T14:27:18.000Z" } ], "analyses": { "keywords": [ "finite density", "cfl phase", "dass sum rule", "axial-vector current correlators", "low temperature corrections" ], "tags": [ "journal article" ], "note": { "typesetting": "RevTeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable", "inspire": 535576 } } }
