Evidence for the collective nature of radial flow in Pb+Pb collisions with the ATLAS detector
ATLAS Collaboration
Anisotropic flow and radial flow are two key probes of the expansion dynamics and properties of the quark-gluon plasma (QGP). While anisotropic flow has been extensively studied, r…
Evidence for the dimuon decay of the Higgs boson in pp collisions with the ATLAS detector
ATLAS Collaboration
A search for the dimuon decay of the Higgs boson is presented based on pp collision data recorded by ATLAS during Run 3 of the Large Hadron Collider, corresponding to an integrated…
Search for neutral long-lived particles that decay into displaced jets in the ATLAS calorimeter in association with leptons or jets using collisions at TeV
ATLAS Collaboration
A search for neutral long-lived particles (LLPs) decaying in the ATLAS hadronic calorimeter using 140 fb of proton-proton collisions at TeV delivered by the LH…
Evidence for longitudinally polarized bosons in the electroweak production of same-sign boson pairs in association with two jets in pp collisions at TeV with the ATLAS detector
The ATLAS Collaboration
This Letter reports the first evidence of production of same-sign boson pairs where at least one of the bosons is longitudinally polarized and the most stringent constraint…
Measurements of and production with Higgs boson decays into bottom quarks and direct constraints on the charm Yukawa coupling in collisions with the ATLAS detector
ATLAS Collaboration
A study of the Higgs boson decaying into bottom quarks () and charm quarks () is performed, in the associated production channel of the Higgs boson…
Search for boosted low-mass resonances decaying into hadrons produced in association with a photon in pp collisions at 13 TeV with the ATLAS detector
ATLAS Collaboration
Many extensions of the Standard Model, including those with dark matter particles, propose new mediator particles that decay into hadrons. This paper presents a search for such low…
