Search for a new pseudoscalar decaying into a pair of bottom and antibottom quarks in top-associated production in =13 TeV proton-proton collisions with the ATLAS detector
ATLAS Collaboration
A search for a pseudoscalar produced in association with a top-quark pair, or in association with a single top quark plus a boson, with the pseudoscalar decaying into -q…
Search for heavy neutral leptons in decays of W bosons using leptonic and semi-leptonic displaced vertices in TeV collisions with the ATLAS detector
ATLAS Collaboration
A search is performed for long-lived heavy neutral leptons (HNLs), produced through the decay of a boson along with a muon or electron. Two channels are explored: a leptonic ch…
Measurement of the top quark mass with the ATLAS detector using events with a high transverse momentum top quark
ATLAS Collaboration
The mass of the top quark is measured using top-antitop-quark pair events with high transverse momentum top quarks. The dataset, collected with the ATLAS detector in proton--proton…
Configuration, Performance, and Commissioning of the ATLAS -jet Triggers for the 2022 and 2023 LHC data-taking periods
ATLAS Collaboration
In 2022 and 2023, the Large Hadron Collider produced approximately two billion hadronic interactions each second from bunches of protons that collide at a rate of 40 MHz. The ATLAS…
Search for charged Higgs bosons produced in top-quark decays or in association with top quarks and decaying via in 13 TeV collisions with the ATLAS detector
ATLAS Collaboration
Charged Higgs bosons produced either in top-quark decays or in association with a top-quark, subsequently decaying via , are searched for in 140 $\text{fb}^…
Observation of production at TeV with the ATLAS detector
ATLAS Collaboration
A search for the production of three massive vector bosons, , in proton-proton collisions at TeV is performed using data with an integrated luminosity…
