1. M. Zubkov ITEP Moscow 2007 10 Tev monopoles and topology of the Standard Model

2. 2 Abstract Standard Model may be defined with the gauge groups We show, that, if the Unification is achieved at Tev (it could be in PUT or ETC), in the cases monopoles with masses of the order of 10 Tev should appear, which may become the lightest topologically stable monopoles. The idea is illustrated by consideration of Petite Unification models.

3. 3 The lattice model for qualitative investigation of this phenomenon based on the Petite Unification Theory is presented 10 Tev monopoles monopoles We expect the percolation transition is present Early Universe

43. 43 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.
