Sphaleron-Bisphaleron bifurcations in a custodial-symmetric two-doublets model
Y. Brihaye
The standard electroweak model is extended by means of a second Brout-Englert-Higgs-doublet. The symmetry breaking potential is chosen is such a way that (i) the Lagrangian possess…
Boson stars in SU(2) Yang-Mills-scalar field theories
Yves Brihaye, Betti Hartmann, Eugen Radu
We present new spherically symmetric solutions of an SU(2) Einstein-Yang-Mills model coupled to a doublet of scalar fields. Sequences of asymptotically flat, Yang-Mills-boson star-…
Yang--Mills sphalerons in all even spacetime dimensions , : =3,4
Yves Brihaye, D. H. Tchrakian
The classical solutions to higher dimensional Yang--Mills (YM) systems, which are integral parts of higher dimensional Einstein--YM (EYM) systems, are studied. These are the gravit…
Bounding Gauged Skyrmion Masses
Yves Brihaye, Christopher Hill, Cosmas Zachos
Normally, standard (ungauged) skyrmion masses are proportional to the coupling of the Skyrme term needed for stability, and so can grow to infinite magnitude with increasing coupli…
Gravitating Yang-Mills dyon vortices in 4+1 spacetime dimensions
Yves Brihaye, Eugen Radu
We consider vortex-type solutions in dimensions of the Einstein gravity coupled to a nonabelian SU(2) field posessing a nonzero electric part. After the dimensional reduction…
Gravity localisation in a 6-dimensional brane world
Betti Hartmann, Yves Brihaye
We study a 6-dimensional Einstein-Born-Infeld-Higgs model. In the limit of infinite Born-Infeld coupling, this model reduces to an Einstein-Abelian-Higgs model, in which gravity lo…
