Observation of a new particle in the search for the Standard Model Higgs boson with the ATLAS detector at the LHC

Georges Aad, +2967 more
- 17 Sep 2012 - 
TL;DR: In this article, a search for the Standard Model Higgs boson in proton-proton collisions with the ATLAS detector at the LHC is presented, which has a significance of 5.9 standard deviations, corresponding to a background fluctuation probability of 1.7×10−9.
Journal ArticleDOI

Combined Measurement of the Higgs Boson Mass in pp Collisions at √s=7 and 8 TeV with the ATLAS and CMS Experiments

Georges Aad, +5120 more
- 14 May 2015 - 
TL;DR: A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H→γγ and H→ZZ→4ℓ decay channels.
Journal ArticleDOI

Direct detection of a break in the teraelectronvolt cosmic-ray spectrum of electrons and positrons

G. Ambrosi, +157 more
- 29 Nov 2017 - 
TL;DR: The direct detection of a spectral break at about 0.9 teraelectronvolts confirms the evidence found by previous indirect measurements, clarifies the behaviour of the CRE spectrum at energies above 1 terAElectronvolt and sheds light on the physical origin of the sub-teraelectronsvolt CREs.
Journal ArticleDOI

Topological cell clustering in the ATLAS calorimeters and its performance in LHC Run 1

Georges Aad, +2891 more
- 24 Jul 2017 - 
TL;DR: Topological cell clustering is established as a well-performing calorimeter signal definition for jet and missing transverse momentum reconstruction in ATLAS and is exploited to apply a local energy calibration and corrections depending on the nature of the cluster.
Journal ArticleDOI

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √=s=8 TeV with the ATLAS detector

Georges Aad, +2818 more
- 01 Jul 2015 - 
TL;DR: In this article, a search for new phenomena in final states with an energetic jet and large missing transverse momentum was performed using 20.3 fb(-1) of root s = 8 TeV data collected in 2012.
