Trilepton Signal of Minimal Supergravity at the Tevatron including -lepton Contributions Typeset Using Revt E X
نویسنده
چکیده
The trilepton signal with missing transverse energy (3` + E / T , with`= e or) from chargino-neutralino (1 0 2) associated production and decays is studied for the upgraded Fermilab Tevatron Collider with 2 TeV center of mass energy and integrated luminosity of 2 fb ?1 (MI) to 20 fb ?1 (TeV33). In some regions of parameter space in the minimal supergravity model, 1 and 0 2 decay dominantly into nal states with leptons via real or virtual ~ 1 sleptons. The contributions from ?leptonic decays increase the trilepton signal from 1 0 2 by at least a factor of two when soft but realistic cuts on lepton transverse momenta are used. With the Main Injector, a trilepton signal can be detected at tan v 2 =v 1 3 for universal masses m 1=2 ; m 0 < 200 GeV.

متن کاملTrilepton Signature of Minimal Supergravity at the Upgraded Tevatron
The prospects for detecting trilepton events (ℓ = e or µ) from chargino-neutralino (χ ± 1 χ 0 2) associated production are investigated for the upgraded Fermilab Tevatron Collider in the context of the minimal supergravity model (mSUGRA). In some regions of parameter space, χ ± 1 and χ 0 2 decay dominantly into final states with τ leptons and the contributions from τ −leptonic decays enhance th...
متن کاملR-parity Violation and Top Quark Polarization at the Fermilab Tevatron Collider Typeset Using Revt E X
The lepton or baryon number violating top quark interactions in the supersymmetric standard model with R parity violation contribute to the process dd̄ → tt̄ at the tree level via the tor u-channel sfermion exchange. Since these interactions are chiral, they induce polarization to the top quark in the tt̄ events at hadron colliders. We show in this article that the polarization can be a useful obs...
متن کاملCosmological relic density from minimal supergravity with implications for collider physics.
Working within the framework of the minimal supergravity model with gauge coupling unification and radiative electroweak symmetry breaking, we evaluate the cosmological relic density from lightest neutralinos produced in the early universe. Our numerical calculation is distinct in that it involves direct evaluation of neutralino annihilation cross sections using helicity amplitude techniques, a...
متن کاملCp Phases in Correlated Trilepton Signal at Tevatron
We study the tri–lepton signal for supersymmetric particle searches at the Teva-tron including the CP phases Φ µ and Φ 1 and the production–decay spin correlations. The phases affect very strongly the production rate and the branching fractions of the leptonic chargino and neutralino decays and, as a result, could lead to a sharp drop in the tri–lepton signal rate. We demonstrate the importance...
