Topological cell clustering in the ATLAS calorimeters and its performance in LH...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

The reconstruction of the signal from hadrons and jets emerging from the proton–proton collisions at the Large Hadron Collider (LHC) and entering the ATLAS calorimeters is based on a three-dimensional topological clustering of individual calorimeter cell signals. The cluster formation follows cell signal-significance patterns generated by electromagnetic and hadronic showers. In this, the clustering algorithm i...


Measurements of top-quark pair differential cross-sections in the eμ channel in...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

This article presents measurements of tt¯ differential cross-sections in a fiducial phase-space region, using an integrated luminosity of 3.2 fb−1 of proton–proton data at a centre-of-mass energy of s√=13 TeV recorded by the ATLAS experiment at the LHC in 2015. Differential cross-sections are measured as a function of the transverse momentum and absolute rapidity of the top quark, and of the transverse momentum...


Search for new phenomena in a lepton plus high jet multiplicity final state the...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

A search for new phenomena in final states characterized by high jet multiplicity, an isolated lepton (electron or muon) and either zero or at least three b-tagged jets is presented. The search uses 36.1 fb−1 of s√=13 TeV proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider in 2015 and 2016. The dominant sources of background are estimated using parameterized extrapolation...


Search for pair production of vector-like top quarks in events with one lepton,...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

The results of a search for vector-like top quarks using events with exactly one lepton, at least four jets, and large missing transverse momentum are reported. The search is optimised for pair production of vector-like top quarks in the Z(→νν) t + X decay channel. LHC pp collision data at a centre-of-mass energy of s√=13 TeV recorded by the ATLAS detector in 2015 and 2016 are used, corresponding to an integrat...


Measurements of the production cross section of a Z boson in association with j...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

Measurements of the production cross section of a Z boson in association with jets in proton–proton collisions at s√=13 TeV are presented, using data corresponding to an integrated luminosity of 3.16 fb−1 collected by the ATLAS experiment at the CERN Large Hadron Collider in 2015. Inclusive and differential cross sections are measured for events containing a Z boson decaying to electrons or muons and produced i...


Measurements of long-range azimuthal anisotropies and associated Fourier coeffi...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

ATLAS measurements of two-particle correlations are presented for √s=5.02 and 13 TeV pp collisions and for √sNN=5.02 TeV p+Pb collisions at the LHC. The correlation functions are measured as a function of relative azimuthal angle Δϕ, and pseudorapidity separation Δη, using charged particles detected within the pseudorapidity interval |η|<2.5. Azimuthal modulation in the long-range component of the correlation f...


Search for Heavy Higgs Bosons A/H Decaying to a Top Quark Pair in pp Collisions...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

A search for heavy pseudoscalar (A) and scalar (H) Higgs bosons decaying into a top quark pair (t¯t) has been performed with 20.3  fb−1 of proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a center-of-mass energy √s=8  TeV. Interference effects between the signal process and standard model t¯t production, which are expected to distort the signal shape from a single p...


Measurement of multi-particle azimuthal correlations in pp, p + Pb and low-mult...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

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 compared to the results obtained for low-multiplicity Pb + Pb collisions at sNN−−−√ = 2.76 TeV. These measurements aim to assess the collective nature of particle production. The measurements ...


Erratum to: Measurement of the charge asymmetry in top-quark pair production in...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

In the original paper, Fig. 4 contains the wrong label preliminary. The label has been fixed, while none of the results have changed.; The online version of the original article can be found under doi:10.1140/epjc/s10052-016-3910-6


Search for direct top squark pair production in events with a Higgs or Z boson,...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

A search for direct top squark pair production resulting in events with either a same-flavour opposite-sign dilepton pair with invariant mass compatible with a Z boson or a pair of jets compatible with a Standard Model (SM) Higgs boson (h) is presented. Requirements on the missing transverse momentum, together with additional selections on leptons, jets, jets identified as originating from b-quarks are imposed ...
