SUSY Particle Production at the Tevatron ∗
نویسنده
چکیده
The determination of the full SUSY QCD corrections to the production of squarks, gluinos and gauginos at the Tevatron is reviewed. The NLO corrections stabilize the theoretical predictions of the various production cross sections significantly and lead to sizeable enhancements of the most relevant cross sections. We discuss the phenomenological consequences of the results on present and future experimental analyses. Contribution to the Workshop Physics at Run II – Supersymmetry/Higgs, 1998, Fermilab, USA.

متن کاملSupersymmetric Electroweak Parity Nonconservation in Top Quark Pair Production at the Fermilab Tevatron
We evaluate the supersymmetric (SUSY) electroweak corrections to the effect of parity nonconservation in qq̄ → tt̄ production at the Fermilab Tevatron predicted by the Minimal Supersymmetric Model (MSSM). We find that the parity nonconserving asymmetry from the SUSY electroweak and SUSY Yukawa loop corrections predicted by the minimal supergravity (mSUGRA) model and the MSSM models with scenarios...
متن کاملThe Reach of Cern Lep2 and Fermilab Tevatron Upgrades for Higgs Bosons in Supersymmetric Models
Luminosity upgrades of the Fermilab Tevatron pp̄ collider have been shown to allow experimental detection of a Standard Model (SM) Higgs boson up to mHSM ∼ 120 GeV via WHSM → lνbb̄ events. This limit nearly saturates the parameter space for many models of weak scale supersymmetry (SUSY) with a minimal particle content. It is therefore interesting to examine the SUSY Higgs reach of future Tevatron...
متن کاملSupersymmetric QCD Parity Nonconservation in Top Quark Pairs at the Tevatron
In the supersymmetry (SUSY) models, because of the mass difference between the leftand right-top squarks, the supersymmetric QCD interactions can generate parity violating effects in the production of tt̄ pairs. We show that SUSY QCD radiative corrections to the parity violating asymmetry in the production rates of the leftand right-handed top quarks via the qq̄ → tt̄ process can reach about 3% at...
