Title: Baryon asymmetry of the Universe and neutrinos
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. I will 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.
