A study of angular correlations in 4-jet final states of hadronic Z0 decays

M. Z. Akrawy, +294 more
TL;DR: In this article, the four-jet final states of hadronicZ0 decays, observed ine+e− annihilation around 91 GeV center of mass energy, are analyzed in terms of observables that are sensitive to the non-abelian gauge structure of QCD.
Journal ArticleDOI

Beam-induced and cosmic-ray backgrounds observed in the ATLAS detector during the LHC 2012 proton-proton running period

Georges Aad, +2865 more
TL;DR: In this paper, various observations on beam-induced and cosmic-ray backgrounds in the ATLAS detector during the LHC 2012 proton-proton run were discussed and the correlations between background and residual pressure of the beam vacuum were revisited.
Journal ArticleDOI

Search for the standard model Higgs boson produced in association with a vector boson and decaying into a tau pair in pp collisions at s =8 TeV with the ATLAS detector

Georges Aad, +2911 more
- 17 May 2016 - 
TL;DR: In this paper, a search for the standard model Higgs boson produced in association with a vector boson with the decay H -> tau tau is presented, and the data correspond to 20.3 fb(-1) of integrated luminosity from proton-proton collisions at root s = 8 TeV recorded by the ATLAS experiment at the LHC during 2012.
Journal ArticleDOI

Erratum: "Measurement of the inclusive jet cross-section in proton-proton collisions at √s = 7 TeV using 4.5 fb−1 of data with the ATLAS detector"

Georges Aad, +2923 more
TL;DR: In this paper, it was found that the nonperturbative corrections calculated using Pythia with the Perugia 2011 tune did not include the effect of the underlying event and the affected correction factors were recomputed using the Pythia 6.427 generator.
Journal ArticleDOI

Constraints on high-energy neutrino emission from SN 2008D

Rasha Abbasi, +260 more
TL;DR: In this paper, a boosted decision tree classifier was trained with simulated signal and experimental background data to find neutrino signals in temporal and spatial correlation with the observed X-ray flash of SN 2008D.
