The elliptic flow of prompt and non-prompt J/ψ was measured in the dimuon decay channel in Pb+Pb collisions at √sNN = 5.02 TeV with an integrated luminosity of 0.42 nb−1 with the ATLAS detector at the LHC. The prompt and ...

Searches for the exclusive decays of the Higgs and Z bosons into a J/ψ, ψ(2S), or ϒ(nS) (n = 1, 2, 3) meson and a photon are performed with a pp collision data sample corresponding to an integrated luminosity of 36.1 fb−1 ...

A search for the decay of the Standard Model Higgs boson into a b¯ b pair when produced in association with a W or Z boson is performed with the ATLAS detector. The data, corresponding to an integrated luminosity of 79.8 ...

A search for supersymmetric partners of top quarks decaying as t˜1 → cχ˜ 0 1 and supersymmetric partners of charm quarks decaying as ˜c1 → cχ˜ 0 1, where χ˜ 0 1 is the lightest neutralino, is presented. The search uses ...

A search for new phenomena in events with two same-charge leptons or three leptons and jets identified as originating from b-quarks in a data sample of 36.1 fb−1 of pp collisions at √ s = 13 TeV recorded by the ATLAS ...

A search for vectorlike quarks is presented, which targets their decay into a Z boson and a thirdgeneration Standard Model quark. In the case of a vectorlike quark T (B) with charge þ2=3e (−1=3e), the decay searched for ...

A search for electroweak production of supersymmetric particles is performed in two-lepton and threelepton final states using recursive jigsaw reconstruction, a technique that assigns reconstructed objects to the most ...

A search for pair production of the supersymmetric partners of the Higgs boson (higgsinos H˜ ) in gaugemediated scenarios is reported. Each higgsino is assumed to decay to a Higgs boson and a gravitino. Two complementary ...

Searches for non-resonant and resonant Higgs boson pair production are performed in the γ γ W W∗ channel with the final state of γ γ ν j j using 36.1 fb−1 of proton– proton collision data recorded at a centre-of-mass ...

Direct searches for lepton flavor violation in decays of the Z boson with the ATLAS detector at the LHC are presented. Decays of the Z boson into an electron or muon and a hadronically decaying τ lepton are considered. The ...
