Electroweak monopoles and electroweak baryogenesis
  We describe electroweak monopoles within the Born-Infeld extension of
$SU(2)_L\times U(1)_Y$ electroweak theory. We argue for topological stability
of these monopoles and computed their mass in terms of the Born-Infeld mass
parameters. We then propose a new mechanism for electroweak baryogenesis which
takes advantage of the following salient features of the electroweak monopoles:
(i) monopoles support extra CP violation in the topological sector of the
electroweak theory; (ii) they mediate unsuppressed baryon number violating
interactions; (iii) non-thermal production of monopoles during the electroweak
phase transitions generates departure from thermal equilibrium. We demonstrate
that the observed baryon asymmetry of the universe can be explained in our
theory in the presence of electroweak monopoles of mass $M\sim 10^{4}$ TeV.
