Neutrino Masses and Leptogenesis from R Parity Violation
نویسنده
چکیده
In R parity violating supersymmetry (conserving baryon number B but violating lepton number L), Majorana neutrino masses may arise at tree level, in one loop, and in two loops. The L violating interactions work together with the B + L violating electroweak sphalerons to erase any preexisting B or L asymmetry of the Universe. To have successful leptogenesis nevertheless, a specific scenario is proposed.

Leptogenesis from Neutralino Decay with Nonholomorphic R-Parity Violation
In supersymmetric models with lepton-number violation, hence also R-parity violation, it is easy to have realistic neutrino masses, but then leptogenesis becomes difficult to achieve. After explaining the general problems involved, we study the details of a model which escapes these constraints and generates a lepton asymmetry, which gets converted into the present observed baryon asymmetry of ...
متن کاملLeptogenesis bound on neutrino masses in left-right symmetric models with spontaneous D-parity violation
We study the baryogenesis via leptogenesis in a class of left-right symmetric models, in which D-parity is broken spontaneously. We first discuss the consequence of the spontaneous breaking of D-parity on the neutrino masses. Than we study the lepton asymmetry in various cases, from the decay of right handed neutrino as well as the triplet Higgs, depending on their relative masses they acquire ...
متن کاملR parity violation assisted thermal leptogenesis in the seesaw mechanism.
Successful leptogenesis within the simplest type I supersymmetric seesaw mechanism requires the lightest of the three right-handed neutrino supermultiplets to be heavier than approximately 10(9) GeV. Thermal production of such (s)neutrinos requires very high reheating temperatures which result in an overproduction of gravitinos with catastrophic consequences for the evolution of the Universe. I...
متن کاملLeptogenesis: Neutrinos and New Lepton Flavor Violation at the Tev Energy Scale
Leptogenesis, i.e. the creation of a lepton asymmetry in the early Universe, may occur through the decay of heavy singlet (right-handed) neutrinos. If we require it not to be erased by physics beyond the Standard Model at the TeV energy scale, then only 2 candidates are possible if they are subgroups of E6. These 2 solutions happen to be also the only ones within 1σ of the atomic parity violati...
متن کاملSupersymmetric Lepton Flavor Violation and Leptogenesis
We present and discuss constraints on supersymmetric type I seesaw models imposed by neutrino data, charged lepton flavor violation and thermal leptogenesis. 1 Supersymmetric seesaw mechanism and slepton mass matrix The observed neutrino oscillations imply the existence of neutrino masses and lepton flavor mixing, and give hints towards physics beyond the Standard Model. For example, the smalln...
