Description
We consider an isolated electroweak monopole solution within the Standard Model with a
non-linear Born-Infeld extension of the hypercharge gauge field. Monopole (and dyon) solutions
in such an extension are regular and their masses are predicted to be proportional
to the Born-Infeld mass parameter. We argue that cosmological production of electroweak
monopoles in a narrow mass range may delay the electroweak phase transition and make it more strongly first order while satisfying nucleosynthesis constraints.
