Neutrino-induced lepton flavor violation in gauge-mediated supersymmetry breaking
نویسندگان
چکیده
Gauge-mediated supersymmetry breaking is known to greatly suppress flavor changing neutral current effects. However, we show that gauge mediation in the context of leptogenesis implies potentially large lepton flavor violating signals. If the heavy righthanded neutrinos that participate in leptogenesis are lighter than the messenger scale of gauge mediation, they will induce flavor off-diagonal masses to the sleptons which in turn can induce large effects in μ → eγ, τ → μγ, and μ− e conversion in nuclei. We demonstrate this result and compute numerically the lepton-flavor violating decay and conversion rates in scenarios of direct gauge mediation. hep-ph/0310148 October 2003

Gauge and Yukawa mediated supersymmetry breaking in the triplet seesaw scenario.
We propose a novel supersymmetric unified scenario of the triplet seesaw mechanism where the exchange of the heavy triplets generates both neutrino masses and soft supersymmetry breaking terms. Our framework is very predictive since it relates neutrino mass parameters, lepton-flavor-violation in the slepton sector, sparticle and Higgs spectra, and electroweak symmetry breakdown. The phenomenolo...

The gauge-mediated supersymmetry breaking mechanism is one of the most reliable scenario which naturally suppresses the large flavor changing neutral current and CP violation in the supersymmetric standard model. When the messenger fields have suitable B − L charges, the radiative correction naturally induces the Zee-like neutrino mass matrix, which provides tiny neutrino masses and large lepto...
متن کاملMeV Tau Neutrino in Gauge Mediated Supersymmetry Breaking Model
A supersymmetric model which naturally accommodates MeV tau neutrino within the framework of gauge mediated supersymmetry breaking is described. The lepton number violation is originally introduced in the messenger sector of the theory. A large slepton-Higgs mixing mass and a small lepton-higgsino mixing mass are generated at one-loop. Scalar tau neutrino has non-vanishing vacuum expectation va...
متن کاملZee Neutrino Mass Matrix in the Gauge Mediated Supersymmetry Breaking Scenario
It is well known that Zee type neutrino mass matrix can derive bi-maximal neutrino mixing for three neutrinos. We give the reconciliation of this model with the gauge mediated supersymmetry breaking scenario, which naturally suppresses the large flavor changing neutral current and CP violation in the supersymmetric standard model. When the messenger fields have suitable B − L charges, the radia...
متن کاملPhoton signatures for low energy supersymmetry breaking and broken R-parity
The possible phenomenological consequences of R-parity violating interactions in the framework of low energy supersymmetry breaking are studied. It is pointed out that even very weak R-parity violation would completely overshadow one of the basic signatures of low energy supersymmetry breaking models, that is the decay of the next to lightest supersymmetric particle into a photon (lepton) and m...
