Baryon Number Violation in Particle Decays
It has been argued in the past that in baryogenesis via out-of-equilibrium decays one must consider loop diagrams that contain more than one baryon number violating coupling. In this note we argue that the requirement with regard to baryon number violating couplings in loop diagrams is that the interaction between the intermediate on-shell particles and the final particles should correspond to ...
متن کامل2002 Electroweak Baryon Number Violation
The conditions for baryogenesis in the early universe are well-known (cf. Refs. [1, 2]): 1. C and CP violation, 2. thermal nonequilibrium, 3. violation of baryon number conservation. How realistic are these requirements? Well, noninvariance under the charge conjugation transformation (C) and the combined charge conjugation and parity reflection transformation (CP) have been observed in the labo...
متن کاملBaryon Number Violation and String Hadronization
In supersymmetric scenarios with broken R-parity, baryon number violating sparticle decays are possible. We report on the development of a framework allowing detailed studies with special attention given to the hadronization phase. In our model, implemented in the Pythia event generator, the baryon number violating vertex is associated with the appearance of a junction in the colour confinement...
متن کاملBaryon Number Violation Involving Higher Generations
Proton decay was suggested 30 years ago as a means to probe physics at very high energy scale, such as [1] Grand Unified Theories (GUT). Baryon number violation is also a key ingredient [2] to understand the baryon asymmetry of our Universe. Experimental search for proton decay has yielded [3] only limits so far, albeit very stringent ones, and improvement requires huge underground facilities. ...
