Anomaly detection search for new resonances decaying into a Higgs boson and a generic new particle X in hadronic final states using s=13 TeV pp collisions with the ATLAS detector
(American Physical Society (APS), 2023-09-01)
A search is presented for a heavy resonance
Y
decaying into a Standard Model Higgs boson
H
and a new particle
X
in a fully hadronic final state. The full Large Hadron Collider run 2 dataset of proton-proton ...
Measurement of the cross-sections of the electroweak and total production of a Zγ pair in association with two jets in pp collisions at s = 13 TeV with the ATLAS detector
(Elsevier, 2023-10)
This Letter presents the measurement of the fiducial and differential cross-sections of the electroweak production of a Zγ pair in association with two jets. The analysis uses 140 fb−1 of LHC proton–proton collision data ...
Evidence of off-shell Higgs boson production from ZZ leptonic decay channels and constraints on its total width with the ATLAS detector
(Elsevier, 2023-10)
This Letter reports on a search for off-shell production of the Higgs boson using 139
of pp collision data at
13 TeV collected by the ATLAS detector at the Large Hadron Collider. The signature is a pair of Z bosons, ...
Search for the Zγ decay mode of new high-mass resonances in pp collisions at s = 13 TeV with the ATLAS detector
(Elsevier, 2023-12-01)
This letter presents a search for narrow, high-mass resonances in the Zγ final state with the Z boson decaying into a pair of electrons or muons. The
TeV pp collision data were recorded by the ATLAS detector at the CERN ...
Pursuit of paired dijet resonances in the Run 2 dataset with ATLAS
(American Physical Society (APS), 2023-12-01)
New particles with large masses that decay into hadronically interacting particles are predicted by many models of physics beyond the Standard Model. A search for a massive resonance that decays into pairs of dijet resonances ...
