Photon 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...
متن کاملLow-Energy Supersymmetry at Future Colliders
We classify the variety of low-energy supersymmetric signatures that can be probed at future colliders. We focus on phenomena associated with the minimal supersymmetric extension of the Standard Model. The structure of the supersymmetry-breaking introduces additional model assumptions. The approaches considered here are supergravity-mediated and gauge-mediated supersymmetry-breaking. Alternativ...
متن کاملReconstructing Supersymmetric Theories at High Energy Scales
We have studied the reconstruction of supersymmetric theories at high scales by evolving the fundamental parameters from the electroweak scale upwards. Universal minimal supergravity and gauge mediated supersymmetry breaking have been taken as representative alternatives. Pseudo-fixed point structures require the low–energy boundary values to be measured with high precision. 1. Supersymmetric t...
متن کاملSimple Gauge-mediated Models with Local Minima
We describe a simple class of supersymmetric gauge theories that can act as supersymmetry-breaking sectors for gauge-mediated supersymmetry breaking. The models have a local supersymmetry-breaking minimum along a direction in field space where a singlet gets a large expectation value. The potential along this direction has a runaway behavior stabilized by supersymmetry breaking in the effective...
متن کاملDynamical Supersymmetry Breaking and Low Energy Gauge Mediation
Dynamical breaking of supersymmetry was long thought to be an exceptional phenomenon, but recent developments have altered this view. A question of great interest in the current framework is the value of the underlying scale of supersymmetry breaking. The “little hierarchy” problem suggests that supersymmetry should be broken at low energies. Within one class of models, low energy breaking be a...
