Description
The nature of dark matter and its properties remains one of the most important open questions in modern physics. Under a theorized analogue of Standard Model QCD, high energy proton-proton collisions at the LHC could produce a unique signature consisting of two beams or ‘jets’ of Standard Model particles, and two composed of dark matter. The dark matter particles would then decay back into SM particles over macroscopic distances within the ATLAS detector. These dark matter collimated beams are referred to as emerging jets as the visible SM components would ‘emerge’ throughout the detector components. The detection of emerging jets would provide evidence of particle dark matter created at the LHC and open up new strategies to investigate this phenomenon.
Using √s = 13 TeV proton-proton collision ATLAS data recorded from 2015 to 2018, the results of a search for emerging jets will be presented. The theoretical motivations, analysis strategies, and search results will be discussed. Although the presence of emerging jets was not detected, new limits on the possible parameter space were set, excluding many models.
