“Search for new phenomena in events with an energetic jet and missing transverse momentum in pp collisions at √s=13 TeV with the ATLAS detector ” has been submitted to PRD.

This paper describes a search for new physics in final states with an energetic jet and large missing transverse momentum (MET) in proton-proton collisions at √s=13 TeV at the LHC, based on data corresponding to an integrated luminosity of 139 fb−1 collected by the ATLAS detector during 2015-2018. In addition to an increase of almost a factor of four in the data size, the analysis implements a number of improvements in the signal selection and the background determination leading to enhanced sensitivity. The analysis also reached high precision in the background prediction uncertainty of 1.5% at low MET and 4.2% at high MET. The measurements are compatible with the SM predictions, the results are interpreted as an exclusion limit for different signal models.
