Abstract
ATLAS recent results obtained at the LHC on inclusive jet and dijet production at s=13TeV, on transverse energy-energy correlations and on azimuthal decorrelations at s=8TeV are discussed. The latter two are used to determine the strong coupling constant and to probe its running up to scales of order 2 TeV.
Highlights
ATLAS recent results obtained at the LHC on inclusive jet √and dijet production at s = 13 TeV, on transverse energy-energy correlations and on azimuthal decorrelations at s = 8 TeV are discussed
300 GeV < mi j < 9 TeV, y∗ < 3.0 and HT2 > 200 GeV have been obtained using pairing of jet triggers
Mi j denotes the mass of jets i and j, y∗ is defined as usual as y∗ = |y1 − y2|/2 and HT2 denotes the scalar sum of the transverse momenta of the two leading jets
Summary
At the LHC, ATLAS [1] has recently measured inclusive jet and dijet production at 13 TeV [2]. The dominant experimental systematic effects are those due to jet the energy scale (JES) [3]. The dominant theoretical systematic uncertainties are due to the choice of the renormalization and factorization scale They are found to be at the few percent level unless you approach the high end kinematical limits in transverse momentum or dijet mass. Fair agreement between data for inclusive jet production and NLO pQCD predictions is found in individual bins with p-values in the percent range. Some tension appears when considering all data points accross pT and rapidity This calls for a good understanding of the correlations between experimental and theoretical systematic uncertainties. No significant differences between the inclusive jet cross-sections and the NNLO calculations [5] are observed when using pTjet as the renormalization scale. The p-values for individual bins are typically larger than 50% and 5 − 10% for a global fit
