Determination of the strong coupling constant from transverse energy-energy correlations in multijet events at CMS = 13 TeV with the ATLAS detector
Original language description
Measurements of transverse energy-energy correlations and their associatedazimuthal asymmetries in multijet events are presented. The analysis is performed usinga data sample corresponding to 139 fb-1 of proton-proton collisions at a centre-of-massenergy of ps = 13TeV, collected with the ATLAS detector at the Large Hadron Collider.The measurements are presented in bins of the scalar sum of the transverse momentaof the two leading jets and unfolded to particle level. They are then compared to nextto-next-to-leading-order perturbative QCD calculations for the first time, which featurea significant reduction in the theoretical uncertainties estimated using variations of therenormalisation and factorisation scales. The agreement between data and theory is good,thus providing a precision test of QCD at large momentum transfers Q. The strongcoupling constant s is extracted as a function of Q, showing a good agreement withthe renormalisation group equation and with previous analyses. A simultaneous fit toall transverse energy-energy correlation distributions across different kinematic regionsyields a value of s(mZ) = 0.1175 +- 0.0006 (exp.)+0.0034-0.0017 (theo.), while the global fit to theasymmetry distributions yields s(mZ) = 0.1185 +- 0.0009 (exp.)+0.0025-0.0012 (theo.).
