Abstract
Final states with two jets represent one of the main channels when searching for new phenomena in high-energy experiments, because of the high statistics. Dijets events are recorded by ATLAS during the Run2 period at the centre-of-mass energy of 13 TeV. Invariant-mass and angular distributions are analyzed and compared to Standard Model background predictions, seeking for evidence of New Physics signals over the dominant QCD contribution. Information from the dijet angular correlations has been deployed to improve the sensitivity towards broad resonances. Results are interpreted in the context of Standard Model extensions, focusing on a particular dark-matter model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
