Abstract

Our Universe is charge-asymmetric: it contains no antimatter in amounts comparable to matter. This fact provides cosmological evidence for the nonconservation of baryon number as well as for C and CP breaking. We review the problem of the matter-antimatter asymmetry of the Universe and the ideas proposed for its solution motivated by the discoveries in neutrino physics.

Abstract

The possibility of creating baryon asymmetry at the electroweak phase transition in the minimal supersymmetric standard model is considered for the case when right-handed squarks are much lighter than left-handed ones. It is shown that the usual requirement v(T_c)/T_c > 1 for baryogenesis can be satisfied in a range of the parameters of the model, consistent with present experimental bounds., Latex file, 11 pages, 2 postscript figures
