Theoretical and phenomenological implications of R-parity violation in supersymmetric
theories are discussed in the context of particle physics and cosmology. Fundamental …

We review recent progress in the study of the anomalous baryon number non-conservation
at high temperatures and in high-energy collisions. Recent results on high temperature …

We analyze the scenario of baryogenesis through leptogenesis induced by the out-of-
equilibrium decays of heavy Majorana neutrinos and pay special attention to CP violation …

Supersymmetry or SUSY, one of the most beautiful recent ideas of physics, predicts
sparticles existing as superpartners of particles. This book gives a theoretical and …

Cosmological implications of neutrinos are reviewed. The following subjects are discussed
at a different level of scrutiny: cosmological limits on neutrino mass, neutrinos and primordial …

An introduction to explicit <Emphasis Type="Italic">R </Emphasis>-parity violation Page 1
PRAMANA 9 Indian Academy of Sciences Vol. 51, Nos 1 & 2, --journal of July/August 1998 …

The Hubble expansion of galaxies, the 2.73 K black-body radiation background and the
cosmic abundances of the light elements argue for a hot, dense origin of the universe-the …

Baryogenesis by heavy-neutrino decay and sphaleron reprocessing of both baryon and
lepton number is reconsidered, paying special attention to the flavour structure of the …

Analytic expressions of lepton-flavour-and lepton-number-violating decays of charged
leptons are derived in the context of general SU (2) L⊗ U (1) Y seesaw scenarios that are …

We study minimal scenarios of resonant leptogenesis near the electroweak phase transition.
These models offer a number of testable phenomenological signatures for low-energy …
