Search for new phenomena with large jet multiplicities and missing transverse momentum using large-radius jets and flavour-tagging at ATLAS in 13 TeV pp collisions
(2017)
A search is presented for particles that decay producing a large jet multiplicity and invisible particles. The event selection applies a veto on the presence of isolated electrons or muons and additional requirements on ...
Measurement of the tt¯ γ production cross section in proton-proton collisions at √s=8 TeV with the ATLAS detector
(2017)
The cross section of a top-quark pair produced in association with a photon is measured in proton-proton collisions at a centre-of-mass energy of s=8 TeV with 20.2 fb−1 of data collected by the ATLAS detector at the Large ...
Measurement of multi-particle azimuthal correlations in pp,p + Pb and low-multiplicity Pb + Pb collisions with the ATLASdetector
(2017)
Multi-particle cumulants and corresponding Fourier harmonics are measured for azimuthal angle distributions of charged particles in pp collisions at s = 5.02 and 13 TeV and in p + Pb collisions at sNN = 5.02 TeV, and ...
Measurement of the k t splitting scales in Z → ℓℓ events in pp collisions at √s=8 TeV with the ATLAS detector
(2017)
A measurement of the splitting scales occuring in the kt jet-clustering algorithm is presented for final states containing a Z boson. The measurement is done using 20.2 fb−1 of proton-proton collision data collected at a ...
Measurement of jet shapes in top-quark pair events at √s = 7 TeV using the ATLAS detector
(2013)
A measurement of jet shapes in top-quark pair events using 1.8 fb−1 of √s = 7 TeV pp collision data recorded by the ATLAS detector at the LHC is presented. Samples of top-quark pair events are selected in both the single-lepton ...
Search for dark matter produced in association with a hadronically decaying vector boson in pp collisions at √s=13 TeV with the ATLAS detector
(2017)
A search is presented for dark matter produced in association with a hadronically decaying W or Z boson using 3.2 fb−1 of pp collisions at s=13 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with ...
Measurement of inclusive and differential cross sections in the H → ZZ * → 4ℓ decay channel in pp collisions at √s=13 TeV with the ATLAS detector
(2017)
Inclusive and differential fiducial cross sections of Higgs boson production in proton-proton collisions are measured in the H → ZZ* → 4ℓ decay channel. The proton-proton collision data were produced at the Large Hadron ...
Search for new high-mass phenomena in the dilepton final state using 36 fb−1 of proton-proton collision data at √s=13 TeV with the ATLAS detector
(2017)
A search is conducted for new resonant and non-resonant high-mass phenomena in dielectron and dimuon final states. The search uses 36.1 fb−1 of proton-proton collision data, collected at s=13 TeV by the ATLAS experiment ...
Search for top quark decays t → qH, with H → γγ, in √s=13 TeV pp collisions using the ATLAS detector
(2017)
This article presents a search for flavour-changing neutral currents in the decay of a top quark into an up-type (q = c, u) quark and a Higgs boson, where the Higgs boson decays into two photons. The proton-proton collision ...
Search for new phenomena in events containing a same-flavour opposite-sign dilepton pair, jets, and large missing transverse momentum in √s=13 TeV pp collisions with the ATLAS detector
(2017)
Two searches for new phenomena in final states containing a same-flavour opposite-sign lepton (electron or muon) pair, jets, and large missing transverse momentum are presented. These searches make use of proton–proton ...
