Abstract (data abstract)
CERN-LHC. Asymptotic freedom beyond the TeV scale and determination of the strong coupling constant from Transverse Energy-Energy Correlations in multijet events at 13 TeV with the ATLAS detector. The data sample with integrated luminosity of 139 inverse fb corresponds to proton-proton collisions collected by ATLAS during the LHC Run-2. Jets are reconstructed using the anti-kt algorithm with jet radius 0.4. The data sample is binned in HT2 defined as the sum of the transverse momentum of the two leading jets. The theoretical predictions are calculated at NNLO in perturbative QCD. The selection criteria are defined as: - HT2 > 1 TeV - ptJet > 60 GeV - |etaJet| < 2.4
