The equation's kernel contains a one-gluon exchange interaction and a covariant generalization of a linear confining potential with a mixed scalar, pseudoscalar, and vector Lorentz structure, characterized by a continuous mixing parameter. We investigate to what extent the Lorentz structure of the confining kernel can be determined by fitting the mixing parameter to the meson spectrum.", "revisions": [ { "version": "v1", "updated": "2017-08-29T16:16:37.000Z" } ], "analyses": { "keywords": [ "heavy-light mesons", "quark-antiquark interaction", "covariant spectator theory", "mixing parameter", "quark-antiquark bound states" ], "tags": [ "conference paper" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable" } } }
