متن کاملLeptogenesis from R Parity Nonconservation
It is known that realistic neutrino masses for neutrino oscillations may be obtained from R parity nonconserving supersymmetry. It is also known that such interactions would erase any preexisting lepton or baryon asymmetry of the Universe because of the inevitable intervention of the electroweak sphalerons. We now show how a crucial subset of these R parity nonconserving terms may in fact creat...
متن کاملParity Nonconservation in Polarized Electron
Parity violation has been well established in particle physics for many years, since the 1950's where it was first seen in beta decay processes. The strong and electromagnetic forces are parity conserving, and the experimental evidence that parity was not conserved in weak processes came somewhat as a surprise. The weak forces are responsible for the decay of radioactive nuclei, and it was in t...

متن کاملParity Nonconservation in Relativistic Hydrogenic Ions
Hydrogenic systems are attractive objects for precision measurements of parity nonconservation (PNC) since their simple atomic structure allows for accurate theoretical calculations necessary for relating the observed effects to the standard model. Various possibilities for PNC experiments with hydrogenic ions have been discussed in the literature. Most of the early work dealt with the PNC cont...
