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…

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…
