Quest for gauginos in LHC-Run2 / ATLAS
Despite no significant beyond-the-standard model signatures has been observed in LHC Run1, the discovery of standard model higgs brought a substantial impact on supersymmetry search.
As typical minimal models naively need O(10TeV) light flavor sfermions to reconcile with the 125 GeV higgs, there is a grown motivation in searching gauginos which are almost free from the higgs mass constraint.
Gluino is in particular an interesting target in early Run2 as the production cross-section greatly enhanced by the doubled center-of-mass energy, and the status is quickly evolving along luminosity.
Searching EWKinos, especially for realistic scenarios where the mass spectra is compressed, has more challenges due to their low production cross-section, poor S/N and trigger issue etc., however these are starting to be overcome by recent effort and emerging large data statistics of Run2 and later.
This talk will cover the status-quo and prospect of both searches in the ATLAS experiment, with particular focus on (1) up-to-date analysis of gluino search in 1-lepton final state, and (2) R&D studies on multi-variate techniques for the compressed spectra analysis of EWKino search.
