Search for short- and long-lived axion-like particles in decays with the ATLAS experiment at the LHC
ATLAS Collaboration
Presented is the search for anomalous Higgs boson decays into two axion-like particles (ALPs) using the full Run 2 data set of 140 fb of proton-proton collisions at a centre…
Fiducial and differential cross-section measurements of electroweak production in collisions at TeV with the ATLAS detector
ATLAS Collaboration
The observation of the electroweak production of a boson and a photon in association with two jets, using collision data at the Large Hadron Collider at a centre of mass e…
Measurements of Lund subjet multiplicities in 13 TeV proton-proton collisions with the ATLAS detector
ATLAS Collaboration
This Letter presents a differential cross-section measurement of Lund subjet multiplicities, suitable for testing current and future parton shower Monte Carlo algorithms. This meas…
Search for the non-resonant production of Higgs boson pairs via gluon fusion and vector-boson fusion in the final state in proton-proton collisions at TeV with the ATLAS detector
ATLAS Collaboration
A search for the non-resonant production of Higgs boson pairs in the channel is performed using 140 fb of proton-proton collisions at a cent…
Azimuthal angle correlations of muons produced via heavy-flavor decays in 5.02 TeV Pb+Pb and collisions with the ATLAS detector
ATLAS Collaboration
Angular correlations between heavy-quarks provide a unique probe of the quark-gluon plasma created in ultra-relativistic heavy-ion collisions. Results are presented of a measuremen…
Search for invisible particles produced in association with single top quarks in proton-proton collisions at =13 TeV with the ATLAS detector
ATLAS Collaboration
A search for events with one top quark and missing transverse momentum in the final state is presented. The fully hadronic decay of the top quark is explored by selecting events wi…
