Search for squarks and gluinos in final states with jets and missing transverse momentum at √s = 13 TeV with the ATLAS detector

A search for squarks and gluinos in final states containing hadronic jets, missing transverse momentum but no electrons or muons is presented. The data were recorded in 2015 by the ATLAS experiment in √s = 13 TeV proton-proton collisions at the Large Hadron Collider. No excess above the Standard Mod...

The data were recorded in 2015 by the ATLAS experiment in √s = 13 TeV proton-proton collisions at the Large Hadron Collider.

Results are interpreted within simplified models that assume R-parity is conserved and the neutralino is the lightest supersymmetric particle. An exclusion limit at the 95 % confidence level on the mass of the gluino is set at 1.51 TeV for a simplified model incorporating only a gluino octet and the lightest neutralino, assuming the lightest neutralino is massless. For a simplified model involving the strong production of mass-degenerate first- and second-generation squarks, squark masses below 1.03 TeV are excluded for a massless lightest neutralino. These limits substantially extend the region of supersymmetric parameter space excluded by previous measurements with the ATLAS detector. © CERN for the benefit of the ATLAS collaboration 2016. 2016 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_14346044_v76_n7_p_Aaboud http://hdl.handle.net/20.500.12110/paper_14346044_v76_n7_p_Aaboud
