THE BORN-INFELD SPHALERON — •Betti Hartmann1 and Yves Brihaye2 — 1Department of Mathematical Sciences,University of Durham, United Kingdom — 2Faculté des Sciences, Université de Mons-Hainaut, Belgium
The SU(2) electroweak model, in which the standard Yang-Mills coupling is supplemented by a Born-Infeld term, was studied by us in [1]. The deformation of the sphaleron and bisphaleron solutions due to the Born-Infeld term was investigated and new branches of solutions were exhibited. Especially, a new branch of solutions connecting the Born-Infeld sphaleron to the first solution of the Kerner-Gal’tsov series was found.
