AbstractAbstract

Standard Model may be defined with the gauge Standard Model may be defined with the gauge groupgroupss

We show, thatWe show, that, , if the Unification is achieved at if the Unification is achieved at TevTev (it could be in PUT or ETC), in the cases (it could be in PUT or ETC), in the cases

monopoles with masses of the order of 10 Tevmonopoles with masses of the order of 10 Tev shouldshould appear, which may become the lightest appear, which may become the lightest topologically stable monopoles. topologically stable monopoles. The idea is illustrated The idea is illustrated by consideration of by consideration of Petite Unification modelsPetite Unification models..

0. Four versions of the Standard Model with the gauge groups

are indeed different if the space-time has nontrivial topology.

1. Nontrivial topology appears around the worldlines of monopoles of the unified model. If unification is achieved at Tev (ETC or PUT) and the Standard Model has the gauge group or

then such monopoles may appear with masses about 10 Tev. 3. Those topologically stable monopoles may be created during high energy collisions (probably, at the next generation of colliders, or even at LHC) and may be condensed in the early Universe at high temperature.
