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…

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…
