Analytical Computation of Energy-Energy Correlation at Next-to-Leading Order in QCD.
The energy-energy correlation (EEC) between two detectors in e^{+}e^{-} annihilation was computed analytically at leading order in QCD almost 40 years ago, and numerically at next-to-leading order (NLO) starting in the 1980s. We present the first analytical result for the EEC at NLO, which is remarkably simple, and facilitates analytical study of the perturbative structure of the EEC. We provid...

متن کاملPrecision calculation of the next-to-leading order energy-energy correlation function.
The O(αs ) contribution to the Energy-Energy Correlation function (EEC) [1, 2, 3, 4] of e e− → hadrons is calculated to high precision and the results are shown to be larger than previously reported [9, 10, 11, 12, 13]. The consistency with the leading logarithm approximation and the accurate cancellation of infrared singularities exhibited by the new calculation suggest that it is reliable. We...
متن کاملProduction of Transverse Energy from Minijets in Next-to-leading Order Perturbative Qcd
We compute in next-to-leading order (NLO) perturbative QCD the transverse energy carried into the central rapidity unit of hadron or nuclear collisions by the partons freed in the few-GeV subcollisions. The formulation is based on a rapidity window and a measurement function of a new type. The behaviour of the NLO results as a function of the minimum transverse momentum and as a function of the...
متن کاملQCD field strength correlator at the next-to-leading order
The gauge invariant two-point correlation function of the gauge field strength tensor is calculated in perturbation theory at the next-to-leading order. Besides a direct calculation in perturbative QCD we also present a derivation of the correlation function in the heavy quark effective theory. Our results are briefly compared with recent determinations of the field strength correlator on the l...
