 Search for new resonances in mass distributions of jet pairs using 139 fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector A search for new resonances decaying into a pair of jets is reported using the dataset of proton-proton collisions recorded at $\sqrt{s}=13$ TeV with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, corresponding to an integrated luminosity of 139 fb$^{-1}$.

 Status of searches in the long-lived particle and dark sectors, including full run-2 and HL-LHC prospects / Alimena, Juliette (Ohio State U.) /ATLAS, CMS and LHCB Collaborations Particles beyond the standard model can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at the LHC at CERN, these long-lived particles (LLPs) can decay far from the primary proton-proton interaction, or even completely pass through the detector before decaying.

 Determination of jet calibration and energy resolution in proton-proton collisions at $\sqrt{s}$ = 8 TeV using the ATLAS detector / ATLAS Collaboration The jet energy scale, jet energy resolution, and their systematic uncertainties are measured for jets reconstructed with the ATLAS detector in 2012 using proton-proton data produced at a centre-of-mass energy of 8 TeV with an integrated luminosity of 20 fb$^{-1}$.
