The Born-Infeld Sphaleron
Yves Brihaye, Betti Hartmann
We study the SU(2) electroweak model in which the standard Yang-Mills coupling is supplemented by a Born-Infeld term. The deformation of the sphaleron and bisphaleron solutions due…
Bound monopoles in the presence of a dilaton
Yves Brihaye, Betti Hartmann
We study axially symmetric monopoles of both the SU(2) Yang-Mills-Higgs-Dilaton (YMHD) as well as of the SU(2) Einstein-Yang-Mills-Higgs-Dilaton (EYMHD) system. We find that equall…
Axially Symmetric Monopoles and Black Holes in Einstein-Yang-Mills-Higgs Theory
Betti Hartmann, Burkhard Kleihaus, Jutta Kunz
We investigate static axially symmetric monopole and black hole solutions with magnetic charge n > 1 in Einstein-Yang-Mills-Higgs theory. For vanishing and small Higgs selfcoupling…
Dilatonic monopoles and ''hairy'' black holes
Yves Brihaye, Betti Hartmann, Jutta Kunz
We study gravitating monopoles and non-abelian black holes of SU(2) Einstein-Yang-Mills-Higgs theory coupled to a massless dilaton. The domain of existence of these solutions decre…
