Scanning the phenomenological MSSM

A framework to perform scans in the 19-dimensional phenomenological MSSM is developed and used to re-evaluate the ATLAS experiments' sensitivity to R-parity-conserving supersymmetry with LHC Run 2 data ($\sqrt{s}=13$ TeV), using results from 14 separate ATLAS searches. We perform a $\tilde{t}_1$ dedicated scan, only considering models with $m_{\tilde{t}_1}<1$ TeV, while allowing both a neutralino ($\tilde{\chi}_1^0$) and a sneutrino ($\tilde{\nu}$) as lightest supersymmetric particle. No other experimental constraints are applied.
