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…
Search for heavy right-handed Majorana neutrinos in the decay of top quarks produced in protonproton collisions at = 13 TeV with the ATLAS detector
ATLAS Collaboration
A search for heavy right-handed Majorana neutrinos is performed with the ATLAS detector at the CERN Large Hadron Collider, using the 140 of proton-proton collisi…
Search for flavour-changing neutral-current couplings between the top quark and the Higgs boson in multi-lepton final states in 13 TeV collisions with the ATLAS detector
ATLAS Collaboration
A search is presented for flavour-changing neutral-current interactions involving the top quark, the Higgs boson and an up-type quark () with the ATLAS detector at the Large…
