Search for resonant production of dark quarks in the dijet final state with the ATLAS detector
(Springer Nature, 2024-02-16)
This paper presents a search for a new Z′ resonance decaying into a pair of dark quarks which hadronise into dark hadrons before promptly decaying back as Standard Model particles. This analysis is based on proton-proton ...
Software Performance of the ATLAS Track Reconstruction for LHC Run 3
(2024-12-01)
Charged particle reconstruction in the presence of many simultaneous proton–proton (pp) collisions in the LHC is a challenging task for the ATLAS experiment’s reconstruction software due to the combinatorial complexity. ...
Search for the decay of the Higgs boson to a Z boson and a light pseudoscalar particle decaying to two photons
(2024-03-01)
A search for the decay of the Higgs boson to a Z boson and a light, pseudoscalar particle, a, decaying respectively to two leptons and to two photons is reported. The search uses the full LHC Run 2 proton–proton collision ...
