ATLAS SUSY Search in 0-Lepton Channel — •Manfredi Ronzani — Albert-Ludwigs-Universität Freiburg

Many extensions of the Standard Model (SM) include heavy coloured particles, such as the squarks and gluinos of supersymmetric (SUSY) theories, which could be accessible at the Large Hadron Collider (LHC) and detected by ATLAS. Large number of R-parity-conserving models predict squarks and gluinos produced in pairs and decaying through q → q χ₁⁰ and g→ qq χ₁⁰, or via intermediate production of charginos as q → q χ^± and g → qqχ^±, with subsequent chargino decay to W^±χ₁⁰. The neutralino χ₁⁰ is assumed to be the Lightest Supersimmetric Particle (LSP) and escape undetected, resulting in large missing transverse momentum which, in addition to the jets resulting from the quark decays, form the final states investigated in the 0-Lepton SUSY analysis.

This talk presents the latest results of the ATLAS 0-Lepton SUSY analysis using data recorded in 2015 and 2016 by the ATLAS experiment in √s = 13 TeV proton-proton collision during the LHC Run2.
