Quantum gravity effects in particle physics and cosmology

The authors estimate possible violations, at Planck scales, of baryon number conservation, CPT and Pauli principle. They find that in some cases these violations, although small, are within the possibility of observation by means of present experimental techniques. Special attention has to be paid to searches for Pauli principle violation in nuclear transitions as the most sensitive tests. It is found that the observed baryon asymmetry of the Universe could be explained by the possible CPT violation due to quantum gravity
