Evidence of off-shell Higgs boson production from leptonic decay channels and constraints on its total width with the ATLAS detector
ATLAS Collaboration
This Letter reports on a search for off-shell production of the Higgs boson using 139 of collision data at 13 TeV collected by the ATLAS detecto…

Search for heavy resonances in final states with four leptons and missing transverse momentum or jets in collisions at TeV with the ATLAS detector
ATLAS Collaboration
A search for a new heavy boson produced via gluon-fusion in the four-lepton channel with missing transverse momentum or jets is performed. The search uses proton-proton collision d…

Observation of quantum entanglement in top-quark pairs using the ATLAS detector
ATLAS Collaboration
Entanglement is a key feature of quantum mechanics, with applications in fields such as metrology, cryptography, quantum information, and quantum computation. It has been observed…
