The ATLAS experiment at the Large Hadron Collider employs a two-level trigger system to
record data at an average rate of 1 kHz from physics collisions, starting from an initial bunch …

The performance of the jet trigger for the ATLAS detector at the LHC during the 2011 data
taking period is described. During 2011 the LHC provided proton–proton collisions with a …

The design and performance of the inner detector trigger for the high level trigger of the
ATLAS experiment at the Large Hadron Collider during the 2016–2018 data taking period is …

Run-2 of the Large Hadron Collider (LHC) will provide new challenges to track and vertex
reconstruction with higher energies, denser jets and higher rates. Therefore the ATLAS …

During 2015 the ATLAS experiment recorded\(3.8\,{\mathrm {fb}}^{-1}\) of proton–proton
collision data at a centre-of-mass energy of\(13\,{\mathrm {TeV}}\). The ATLAS trigger system …

A bstract Inclusive jet and dijet cross-sections are measured in proton-proton collisions at a
centre-of-mass energy of 13 TeV. The measurement uses a dataset with an integrated …

The luminosity determination for the ATLAS detector at the LHC during Run 2 is presented,
with $ pp $ collisions at $\sqrt {s}= 13$ TeV. The absolute luminosity scale is determined …

A set of three dedicated triggers designed to detect long-lived neutral particles decaying
throughout the ATLAS detector to a pair of hadronic jets is described. The efficiencies of the …

Searches for long-lived particles (LLPs) are among the most promising avenues for
discovering physics beyond the Standard Model at the Large Hadron Collider (LHC) …
