We investigate a simple theory where baryon number (B) and lepton number (L) are local gauge symmetries. In this theory B and L are on the same footing and the anomalies are canceled by adding a single new fermionic generation. There is an interesting realization of the seesaw mechanism ...

Baryon Number and Lepton Number Conservation Laws The current status, both theoretical and experimental, of baryon and lepton number conservation is discussed. Proton decay is examined in detail H Primakoff,SP Rosen - 《Annual Review of Nuclear & Particle Science》 被引量: 118发表: 1981年 Exotic...
The observation that the baryon number and the lepton number are conserved in nature provides strong motivation for associating gauge symmetries to these conserved numbers. This endeavor requires that the gauge group of electroweak interactions be extended from (2)(1)to (2)(1)(1)(1)where (1)...

Simple models are proposed where the baryon and lepton number are gauged and spontaneously broken near the weak scale. The models use a fourth generation t
In the presence of rapid fermion-number violation due to nonperturbative electroweak effects certain relations between the baryon number of the Universe and the lepton numbers of the Universe are predicted. In some cases the electron-neutrino asymmetry is exactly specified in terms of the baryon asym...
These are two of the very large variety of final states that the proton can disintegrate into while maintaining the conservation of all quantum numbers except baryon number and lepton number (an equivalent quantum number carried by leptons such as electrons, muons, and tau leptons). The stability...
numberviolationneutrinosNeutrinoless double beta decay, lepton number violating collider processes and the Baryon Asymmetry of the Universe (BAU) are intimately related. In particular, lepton number violating processes at low energies in combination with sphaleron transitions will typically erase any pre...
