Determination of spin and parity of the Higgs boson in the WW∗→eνμν decay chann...

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

Studies of the spin and parity quantum numbers of the Higgs boson in the WW∗→eνμν final state are presented, based on proton--proton collision data collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 20.3 fb−1 at a centre-of-mass energy of s√=8 TeV. The Standard Model spin-parity JCP=0++ hypothesis is compared with alternative hypotheses for both spin and C...


Jet energy measurement and its systematic uncertainty in proton-proton collisio...

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

The jet energy scale (JES) and its systematic uncertainty are determined for jets measured with the ATLAS detector using proton–proton collision data with a centre-of-mass energy of s√=7 TeV corresponding to an integrated luminosity of 4.7 fb −1 . Jets are reconstructed from energy deposits forming topological clusters of calorimeter cells using the anti- kt algorithm with distance parameters R=0.4 or R=0.6 , a...


Measurement of the production and lepton charge asymmetry of W bosons in Pb plu...

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

A measurement of W boson production in lead-lead collisions at sNN−−−√=2.76 TeV is presented. It is based on the analysis of data collected with the ATLAS detector at the LHC in 2011 corresponding to an integrated luminosity of 0.14 nb−1 and 0.15 nb−1 in the muon and electron decay channels, respectively. The differential production cross-sections and lepton charge asymmetry are each measured as a function of t...


ATLAS Run 1 searches for direct pair production of third-generation squarks at ...

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

This paper reviews and extends searches for the direct pair production of the scalar supersymmetric partners of the top and bottom quarks in proton--proton collisions collected by the ATLAS collaboration during the LHC Run 1. Most of the analyses use 20 fb−1 of collisions at a centre-of-mass energy of s√=8 TeV, although in some case an additional 4.7 fb−1 of collision data at s√=7 TeV are used. New analyses are...


Observation and measurements of the production of prompt and non-prompt J/ψ mes...

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

The production of a Z boson in association with a J/ψ meson in proton--proton collisions probes the production mechanisms of quarkonium and heavy flavour in association with vector bosons, and allows studies of multiple parton scattering. Using 20.3fb−1 of data collected with the ATLAS experiment at the LHC, in pp collisions at s√=8 TeV, the first measurement of associated Z+J/ψ production is presented for both...


Measurement of the top-quark mass in the fully hadronic decay channel from ATLA...

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

The mass of the top quark is measured in a data set corresponding to 4.6 fb−1 of proton--proton collisions with centre-of-mass energy s√=7 TeV collected by the ATLAS detector at the LHC. Events consistent with hadronic decays of top--antitop quark pairs with at least six jets in the final state are selected. The substantial background from multijet production is modelled with data-driven methods that utilise th...


Search for anomalous production of prompt same-sign lepton pairs and pair-produ...

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

A low-background inclusive search for new physics in events with same-sign dileptons is presented. The search uses proton--proton collisions corresponding to 20.3 fb−1 of integrated luminosity taken in 2012 at a centre-of-mass energy of 8 TeV with the ATLAS detector at the LHC. Pairs of isolated leptons with the same electric charge and large transverse momenta of the type e±e±,e±μ±, and μ±μ± are selected and t...


Measurements of the W production cross sections in association with jets with t...

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

This paper presents cross sections for the production of a W boson in association with jets, measured in proton--proton collisions at s√=7 TeV with the ATLAS experiment at the Large Hadron Collider. With an integrated luminosity of 4.6fb−1, this data set allows for an exploration of a large kinematic range, including jet production up to a transverse momentum of 1 TeV and multiplicities up to seven associated j...


Identification and energy calibration of hadronically decaying tau leptons with...

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

This paper describes the trigger and offline reconstruction, identification and energy calibration algorithms for hadronic decays of tau leptons employed for the data collected from pp collisions in 2012 with the ATLAS detector at the LHC center-of-mass energy s√ = 8 TeV. The performance of these algorithms is measured in most cases with Z decays to tau leptons using the full 2012 dataset, corresponding to an i...


Summary of the ATLAS experiment's sensitivity to supersymmetry after LHC Run 1-...

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

A summary of the constraints from the ATLAS experiment on R-parity-conserving supersymmetry is presented. Results from 22 separate ATLAS searches are considered, each based on analysis of up to 20.3 fb−1 of proton-proton collision data at centre-of-mass energies of s√=7 and 8 TeV at the Large Hadron Collider. The results are interpreted in the context of the 19-parameter phenomenological minimal supersymmetric ...
