“…The production crosssections at the Tevatron are, however, small (tens to hundreds of f b) and the backgrounds are important. So far, none of the Tevatron experiments has reported results from slepton searches in the MSUGRA framework [408]. Their observation from cascade decays is more promising and is presented in section 15. p p/pp → q q, q q, g g, q g + X.…”

This report emphasizes the comparison between supersymmetric models and experiments. A minimal theoretical introduction is included as a guide to the interpretation of results. The existing constraints from low energy measurements, accelerator searches (LEP, Tevatron and HERA) and non-accelerator searches for neutralinos are presented. Prospects for upgrades of these facilities and for the LHC and linear collider are summarized. Most discussions are made in the framework of the minimal supersymmetric standard model inspired by supergravity (MSUGRA). But alternatives such as gauge mediated supersymmetry breaking (GMSB), anomaly mediated supersymmetry breaking (AMSB), models with R-parity violation and even alternatives to supersymmetry are also briefly considered.

“…However, the reader should not assume that this is a necessary condition to the experimental detection of processes of the type (1). In fact, this need not be true, as we shall show that even for M 0 values as large as 500 GeV one can find sizable squark-squark-Higgs production cross sections for M 1/2 up to 200-250 GeV, as long as A 0 is strongly negative, tan β > ∼ 30 and sign(µ) < 0.…”

Higgs production in association with squark pairs in the Minimal Supersymmetric Standard Model at future hadron colliders

We study neutral and charged Higgs boson production in association with stop and sbottom squarks at the Large Hadron Collider, within the Supergravity inspired Minimal Supersymmetric Standard Model. The phenomenological relevance of such reactions is twofold. Firstly, they constitute a novel production mechanism of Higgs particles, either through a decay of a heavier (anti)squark into a lighter one or via a Higgs bremsstrahlung process. Secondly, their production rates are extremely sensitive to the values assumed by the five input parameters of the model, this possibly allowing one to put stringent constraints on the latter. After an exhaustive scan of the parameter space, we find that the majority of such processes could be detectable at high luminosity, provided tan β is large, tan β > ∼ 30 (except in the case oft 1t * 1 h and t 1t * 2 h final states, whose detection is also possible for smaller values), that the universal soft Supersymmetric breaking masses are in the ranges M 0 < ∼ 500 GeV and M 1/2 < ∼ 220 GeV, and that the trilinear couplings are negative, A 0 < 0. We also point out some sizable decay signatures and discuss their Standard Model (SM) backgrounds. Finally, we derive compact analytical formulae of the corresponding scattering matrix elements.

Low Energy Supersymmetry Confronted with Current Experiments: An Overview

This study provides a brief overview of low energy supersymmetry (SUSY) in light of current experimental constraints, such as collider searches, dark matter searches, and muon g−2 measurements. In addition, we survey a variety of low energy supersymmetric models: the phenomenological minimal supersymmetric model (MSSM); the supersymmetric models with cut-off-scale boundary conditions, i.e., the minimal supergravity (mSUGRA) or the constrained MSSM (CMSSM), the gauge mediation of SUSY breaking (GMSB), and the anomaly mediation of SUSY breaking (AMSB), as well as their extensions. The conclusion is that the low energy SUSY can survive all current experimental constraints and remains compelling, albeit suffering from a slight fine-tuning problem. The advanced models such as mSUGRA, GMSB, and AMSB need to be extended if the muon g−2 anomaly comes from new physics.

The Search for Supersymmetry at the Tevatron Collider

Abstract: We review the status of searches for Supersymmetry at the Tevatron Collider. After discussing the theoretical aspects relevant to the production and decay of supersymmetric particles at the Tevatron, we present the current results for Runs Ia and Ib as of the summer of 1997.
