This paper presents a measurement of jet fragmentation functions in 0.49 nb−1 of Pb+Pb collisions and 25 pb−1 of pp collisions at √sNN = 5.02 TeV collected in 2015 with the ATLAS detector at the LHC. These measurements ...

Jet substructure observables have significantly extended the search program for physics beyond the standard model at the Large Hadron Collider. The state-of-the-art tools have been motivated by theoretical calculations, ...

The mass of the Higgs boson is measured in the H → Z Z∗ → 4 and in the H → γγ decay channels with 36.1 fb−1 of proton–proton collision data from the Large Hadron Collider at a centre-of-mass energy of 13 TeV recorded by ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search is conducted for new resonances decaying into a WW or W Z boson pair, where one W boson decays leptonically and the other W or Z boson decays hadronically. It is based on proton-proton collision data with an ...

A search for weakly interacting massive darkmatter particles produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and missing transverse momentum are considered. ...

Measurements of longitudinal flow correlations are presented for charged particles in the pseudorapidity range |η| < 2.4 using 7 µb−1 and 470 µb−1 of Pb+Pb collisions at √sNN = 2.76 and 5.02 TeV, respectively, recorded by ...

Narrow resonances decaying into W W , W Z or Z Z boson pairs are searched for in 36.7 fb−1 of proton– proton collision data at a centre-of-mass energy of √s = 13 TeV recorded with the ATLAS detector at the Large Hadron ...

The efficiency to identify jets containing b-hadrons (b-jets) is measured using a high purity sample of dileptonic top quark-antiquark pairs (tt¯) selected from the 36.1 fb−1 of data collected by the ATLAS detector in 2015 ...

A search is presented for the direct pair production of the stop, the supersymmetric partner of the top quark, that decays through an R-parity-violating coupling to a final state with two leptons and two jets, at least one ...
