Generation of the cosmological baryon asymmetry in SUSY based model with broken R-parity and low scale gravity is considered. The model allows for a long-life time or even stable proton and observable neutron-antineutron oscillations.

We propose a topological inflation model in the framework of supergravity with R invariance. This topological inflation model is not only free from the initial value problem of the inflaton field but also gives low reheating temperature which is favored in supergravity since the overproduction of graviti-nos is avoided. Furthermore, the predicted spectrum of the density fluctuations is generall...

We expose a grave drawback hidden in the standard model of n¯ n transitions in a medium. Correcting it, one improves a limit on the free-space n¯ n oscillation time τ n¯ n by 31 orders of magnitude.
