Abstract
Naturalness arguments for weak-scale supersymmetry favour supersymmet- ric partners of the third generation quarks with masses close to those of their Standard Model counterparts. Real and virtual production of third generation squarks via decay of a gluino can be significant if the mass of the gluino does not exceed the TeV scale. Top or bottom squarks with masses less than a few hundred GeV can also give rise to direct pair production rates at the LHC that can be observed in the 8 TeV data sample recorded by the ATLAS detector. Moreover, many supersymmetric models feature neu- tralinos, charginos and even sleptons with masses less than a few hundred GeV so that they can be observed in the available data sample. The talk presents recent ATLAS re- sults from searches for direct stop and sbottom pair production as well as pair production of charginos, neutralinos and sleptons.
Highlights
The Standard Model (SM) of particles and fields describes experimental data over a large energy range and many of its predictions have been succesfully tested at the per mille level
In the framework of the R-parity-conserving minimal supersymmetric extension of the SM (MSSM), SUSY particles are produced in pairs and the lightest supersymmetric particle (LSP) is stable, providing a possible candidate for dark matter
Such a scenario is possible in the general framework of the phenomenological minimal supersymmetric SM
Summary
The Standard Model (SM) of particles and fields describes experimental data over a large energy range and many of its predictions have been succesfully tested at the per mille level. In the framework of the R-parity-conserving minimal supersymmetric extension of the SM (MSSM), SUSY particles are produced in pairs and the lightest supersymmetric particle (LSP) is stable, providing a possible candidate for dark matter. If the masses of the gluinos and squarks are large, the direct production of charginos, neutralinos and sleptons may dominate the production of SUSY particles at the LHC. Such a scenario is possible in the general framework of the phenomenological minimal supersymmetric SM (pMSSM).
