Abstract

CERN-LHC. A model-independent search is made for the production of new resonances in photon + jet events using 20 fb^-1 of proton-proton LHC data recorded with the ATLAS detector in 2012 at a centre-of-mass energy of sqrt(s) = 8 TeV. The photon + jet mass distribution is compared to a background model fit from data; no significant deviation from the background-only hypothesis is found. Limits are set at 95% credibility level on generic Gaussian-shaped signals and two benchmark phenomena beyond the Standard Model: non-thermal quantum black holes and excited quarks. Non-thermal quantum black holes are excluded below masses of 4.6 TeV and excited quarks are excluded below masses of 3.5 TeV.

Measurement of jet charge in dijet events from sqrt(s)=8 TeV pp collisions with the ATLAS detector

Dataset Aad, Georges

CERN-LHC. Measurements of the jet charge in dijet events in proton-proton collisions at a centre-of-mass energy of 8 TeV with 20.3 fb^-1 of data collected in 2012. The jet charge is a momentum-weighted sum of charges of tracks associated to the jet. The momentum is regulated by an exponent kappa. Measurements are reported for the average and standard deviation of the jet charge distribution as a function of the magnitude of the jet transverse momentum for kappa = 0.3, 0.5, 0.7 and separately for the more forward and more central jets (in pseudo-rapidity). The event selection is minimal, with onlymore »« less

Measurement of the underlying event in jet events from 7 TeV proton-proton collisions with the ATLAS detector

Dataset Aad, Georges

CERN-LHC. Distributions sensitive to the underlying event in QCD jet events have been measured with the ATLAS detector at the LHC, based on 37/pb of proton-proton collision data collected at a centre-of-mass energy of 7 TeV. Charged-particle mean pT and densities of all-particle ET and charged-particle multiplicity and pT have been measured in regions azimuthally transverse to the hardest jet in each event. These are presented both as one-dimensional distributions and with their mean values as functions of the leading-jet transverse momentum from 20 GeV to 800 GeV. The correlation of charged-particle mean pT with charged-particle multiplicity is also studied,more »« less

Journal Article Aad, G. ; Abbott, B. ; Abdallah, J. ; ... - Journal of High Energy Physics (Online)

A search is performed for the production of high-mass resonances decaying into a photon and a jet in 3.2 fb ^-1 of proton-proton collisions at a centre-of-mass energy of (Formula presented.) TeV collected by the ATLAS detector at the Large Hadron Collider. Selected events have an isolated photon and a jet, each with transverse momentum above 150 GeV. No significant deviation of the γ+jet invariant mass distribution from the background-only hypothesis is found. Limits are set at 95% confidence level on the cross sections of generic Gaussian-shaped signals and of a few benchmark phenomena beyond the Standard Model: excited quarksmore »« less
