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…
Estimation of backgrounds from jets misidentified as -leptons using the Universal Fake Factor method with the ATLAS detector
ATLAS Collaboration
Processes with -leptons in the final state are important for Standard Model measurements and searches for physics beyond the Standard Model. The ATLAS experiment at the Large Ha…
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 top-quark pair production in lead-lead collisions at TeV with the ATLAS detector
ATLAS Collaboration
Top-quark pair production is observed in lead-lead (Pb+Pb) collisions at TeV at the Large Hadron Collider with the ATLAS detector. The data sample was r…
A search for triple Higgs boson production in the final state using collisions at TeV with the ATLAS detector
ATLAS Collaboration
A search for the production of three Higgs bosons () in the final state is presented. The search uses of proton-proton collisio…
