Measurement of coherent exclusive production in ultraperipheral Pb+Pb collisions at TeV with the ATLAS detector
ATLAS Collaboration
The ATLAS experiment has performed a measurement of coherent exclusive production in ultraperipheral Pb+Pb collisions at TeV. The data…
Search for Beyond the Standard Model physics with anomaly detection in multilepton final states in collisions at TeV with the ATLAS detector
ATLAS Collaboration
A model-agnostic search for Beyond the Standard Model physics is presented, targeting final states with at least four light leptons (electrons or muons). The search regions are sep…
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}^…
Test of lepton flavour universality in -boson decays into electrons and -leptons using collisions at TeV with the ATLAS detector
ATLAS Collaboration
A measurement of the ratio of the branching fractions, , is performed using a sample of bosons originating from top-quark decays to final s…
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…
