The solutions are obtained as energy-minimizing static spherically symmetric field configurations of unit topological charge. We overcome the difficulty of recovering the full set of boundary conditions by a regularization method which may be applied to other more complicated problems concerning monopoles and dyons in non-Abelian gauge field theories. In a critical coupling situation, an explicit BPS solution is obtained, which may be used to provide energy estimates for non-BPS monopole solutions. In the limit of infinite Higgs coupling parameter, although no explicit construction is available, we establish an existence and uniqueness result for a monopole solution and obtain its energy bounds.", "revisions": [ { "version": "v1", "updated": "2019-09-09T13:49:40.000Z" } ], "analyses": { "subjects": [ "34B40", "35J50", "81T13" ], "keywords": [ "gauge field theory", "dark monopole model", "minimization problem arising", "spherically symmetric field configurations", "static spherically symmetric field" ], "note": { "typesetting": "TeX", "pages": 24, "language": "en", "license": "arXiv", "status": "editable" } } }
