Stop production in R-parity violating supersymmetry at Tevatron
نویسنده
چکیده
Constraints for stop production in R-parity violating supersymmetry at Tevatron have been evaluated using the D0 limits for first generation leptoquarks. Such limits have been converted in constraints for the λ′131 R-parity violating coupling as a function of the stop mass for different Minimal Supersymmetric Standard Model (MSSM) scenarios and compared with Atomic Parity Violation and HERA results. The D0 limits have also been interpreted in terms of constraints on the parameters of the minimal Supergravity model. For a part of the considered MSSM parameter space and for stop mass less than 240 GeV, Tevatron results are the best to date. PACS no: 11.30.Pb, 14.60.Cd, 14.80.Ly

Tevatron Run I SUGRA Results
We present the most recent results of searches for physics beyond the Standard Model using the CDF and D∅ detector in the contest of Supersymmetry (SUSY) with Supergravity (SUGRA) constraints. All results described correspond to analysis performed using the past 1992-1996 Fermilab Tevatron Run I data (roughly 110pb per each experiment). In particular we report on searches for stop decay in tau ...
متن کاملEffects of R-parity-violating supersymmetry in single top production at the Tevatron
We discuss single top quark production via ud̄ → tb̄ at the Fermilab Tevatron in the minimal supersymmetric model with R-parity violation. We find that within the allowed range of coupling constants, the lepton-number violating λ couplings can give rise to observable effects when the slepton mass lies in the range of 200 GeV to 400 GeV. For the baryon-number violating λ couplings, the contributio...
متن کاملAre messages of R-parity violating supersymmetry hidden within top quark signals?
In an R-parity nonconserving supersymmetric theory, the lighter stop can dominantly decay into b&mgr; and btau if R-parity breaking has to explain the neutrino mass and mixing pattern suggested by the data on atmospheric muon neutrinos. This should give rise to dilepton + dijet and single - lepton + jets, signals identical with those of the top quark at the Fermilab Tevatron. One can thus const...
متن کاملStop Lepton Associated Production at Hadron Colliders
At hadron colliders, the search for R-parity violating supersymmetry can probe scalar masses beyond what is covered by pair production processes. We evaluate the next-toleading order SUSY-QCD corrections to the associated stop or sbottom production with a lepton through R-parity violating interactions. We show that higher order corrections render the theoretical predictions more stable with res...
متن کاملImpact of R-parity Violation on Supersymmetry Searches at the Tevatron
We evaluate cross sections for E/T , 1l and various dilepton and multilepton event topologies that result from the simultaneous production of all sparticles at the Tevatron collider, both within the minimal model framework as well as in two different R-parity violating scenarios. Our analysis assumes that these R-violating couplings are small, and that their sole effect is to cause the lightest...
