Exploiting boosted scenarios in supersymmetric searches for squarks and gluinos in final states with jets and missing transverse momentum with the ATLAS detector — •Veronika Magerl — Albert-Ludwigs-Universität Freiburg

Under the hypothesis of R-parity conservation, SUSY partners are produced in pairs and decay to the Lightest Supersymmetric Particle (LSP) which is stable and escapes detection. In a large variety of models this particle is assumed to be the lightest neutralino χ10. The undetected χ10 would result in substantial missing transverse momentum, while the rest of the cascade, originating from the decays of squarks and gluinos, would yield final states with multiple jets and possibly leptons. Some of these models consider a one-step cascade decay of squarks (q) and gluinos (g) via an intermediate production of charginos (χ±), subsequently decaying into W±χ10. Depending on the mass parameter space (g/q, χ±, χ10), W resonances can be boosted such that they are reconstructed as a single jet. This occurs for small mass differences between g/q and χ± and large mass differences between χ± and χ10.

This talk presents the latest studies on design and optimisation of possible signal regions for the ATLAS SUSY 0-Lepton analysis targeting boosted boson signatures in several different SUSY simplified model scenarios.
