# Energy correlations in electron-positron annihilation in quantum chromodynamics: Asymptotically free perturbation theory

@article{Basham1979EnergyCI, title={Energy correlations in electron-positron annihilation in quantum chromodynamics: Asymptotically free perturbation theory}, author={C. Louis Basham and Lowell S. Brown and Stephen D. Ellis and Sherwin T. Love}, journal={Physical Review D}, year={1979}, volume={19}, pages={2018-2045} }

In the absence of infrared mass singularities, the asymptotic behavior of cross sections for ${e}^{+}{e}^{\ensuremath{-}}$ annihilation in quantum chromodynamics can be expressed entirely in terms of the energy dependence of the renormalization-group running coupling constant. Since the theory is asymptotically free, the running coupling vanishes at high energy, and such infrared-finite cross sections can be calculated perturbatively. We extend previous work by calculating, through second order… Expand

Collinear limit of the energy-energy correlator

- Physics
- Physical Review D
- 2019

The energy-energy-correlator (EEC) observable in $e^+e^-$ annihilation measures the energy deposited in two detectors as a function of the angle between the detectors. The collinear limit, where the… Expand

Non-perturbative computation of gluon mini-jet production in nuclear collisions at very high energies

Abstract At very high energies, in the infinite momentum frame and in light-cone gauge, a hard scale proportional to the high parton density arises in QCD. In an effective theory of QCD at small x,… Expand

Abstract We show that the resummation of large perturbative corrections in QCD leads to ambiguities in high energy cross sections that are suppressed by powers of large momentum scales. These… Expand
