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…
Search for Higgs boson decays into a pair of pseudoscalar particles in the final state using collisions at TeV with the ATLAS detector
ATLAS Collaboration
A search for exotic decays of the 125 GeV Higgs boson into a pair of new spin-0 particles, , where one decays into a photon pair and the other into a -lepton pair, is…
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…
Reconstruction and identification of pairs of collimated -leptons decaying hadronically using TeV collision data with the ATLAS detector
ATLAS Collaboration
This paper describes an algorithm for reconstructing and identifying a highly collimated hadronically decaying -lepton pair with low transverse momentum. When two -leptons ar…
