Signals for Gauge Mediated Supersymmetry Breaking Model at an e−e− Collider
نویسندگان
چکیده
We study the pair-production and decay of right handed selectrons within a Gauge Mediated Supersymmetry Breaking Model in polarised e−e− interaction. Detailed analyses of the possible signals and backgrounds are performed for a few selected points in the parameter space. A judicious choice for polarisation of the initial electron beam helps eliminate almost the entire Standard Model background. We also show that phase space distributions can be used to distinguish such a supersummetry breaking scheme from the supergravity inspired models.

Maximizing Hadron Collider Sensitivity to Gauge-Mediated Supersymmetry Breaking Models
We consider typical hadron collider detector signals sensitive to delayed decays of the lightest neutralino to photon plus goldstino and demonstrate the potential for substantially increasing the portion of the general parameter space of a gauge-mediated supersymmetry breaking model that can be probed at the
متن کاملSignals of anomaly mediated supersymmetry breaking in an e − γ collider
We study the signatures of minimal anomaly mediated supersymmetry breaking in an eγ collider. We demonstrate that the associated production of a sneutrino with the lightest chargino leads to a substantially large signal size. The background is negligibly small, though. Even more interestingly, a measurement of the fundamental supersymmetry breaking parameters could be possible. PACS NOS. : 12.6...
متن کاملA Chiral Supersymmetric Standard Model
We propose a supersymmetric extension of the Standard Model with an extra U(1) gauge symmetry, so that all supersymmetric mass terms, including the μ-term, are forbidden by the gauge symmetries. Supersymmetry is broken dynamically which results in U(1) breaking and generation of realistic μ term and soft breaking masses. The additional fields required to cancel the U(1) anomalies are identified...
متن کاملFiltering Out Signals of Gauge-Mediated Supersymmetry Breaking: Can We Always Eliminate Conventional Supersymmetric Effects ?
We investigate the signal γγ + E/ in a high-energy linear ee collider, with a view to differentiating between gauge-mediated supersymmetry breaking and the conventional supersymmetric models. Prima facie, there is considerable chance of confusion between the two scenarios if the assumption of gaugino mass unification is relaxed. We show that the use of polarized electron beams enables one to di...
متن کاملA Solution to the Strong CP Problem with Gauge-Mediated Supersymmetry Breaking
We demonstrate that a certain class of low scale supersymmetric “NelsonBarr” type models can solve the strong and supersymmetric CP problems while at the same time generating sufficient weak CP violation in the K0−K̄0 system. In order to prevent one-loop corrections to θ̄ which violate bounds coming from the neutron electric dipole moment (EDM), one needs a scheme for the soft supersymmetry break...
