Bridging the gap between searches and measurements using the ATLAS detector at the LHC

The Higgs’ boson discovery in 2012 marked a huge milestone for High Energy Physics, but also confirmed the need to address known shortcomings of the Standard Model (SM) of particle physics, which include the lack of a viable candidate for dark matter. Evidence for new physics to solve these shortcomings could appear through either direct searches for new particles predicted in well-motivated SM extensions or through precision measurements of SM processes. Throughout the first two data-taking runs of the LHC no significant deviations from SM predictions were seen through either route enabling stringent constraints on a number of Beyond-the-Standard Model (BSM) physics scenarios. Performing precision SM measurements in search-inspired topologies can enable new constraints on new physics and improve the sensitivity of future searches through improving background modelling. This seminar will discuss the first result from a new effort in the ATLAS collaboration to produce precision measurements in event topologies inspired by searches for supersymmetry (a popular theory for BSM physics), which performed differential measurements of WW production in a phase space complementary to previous ATLAS measurements. As well as discussing these new results and their significance, the importance of a broader programme of extreme measurements throughout run 3 of the LHC (and beyond) will be motivated.
