Implications of Horizontal Symmetries on Baryon Number Violation in Supersymmetric Models

الأصل · EN

The smallness of the quark and lepton parameters and the hierarchy between them could be the result of selection rules due to a horizontal symmetry broken by a small parameter. The same selection rules apply to baryon number violating terms. Consequently, the problem of baryon number violation in Supersymmetry may be solved naturally, without invoking any especially-designed extra symmetry. This mechanism is efficient enough even for low-scale flavor physics. Proton decay is likely to be dominated by the modes K+νᵢ or K⁰μ+(e+), and may proceed at observable rates.
