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
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 theExpand
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
Tests of quantum chromodynamics in hadronic decays of Z0 bosons produced in e+e− annihilation☆
Abstract Hadronic decays of the Z 0 produced in e + e − annihilation are ideal for precise tests of Quantum Chromodynamics. A large number of measurements has been performed, based on the large dataExpand
Construction of infrared finite observables in N = 4 super Yang-Mills theory
In this paper we give all the details of the calculation that we presented in our previous paper [58], where the infrared structure of the maximally helicity violating gluon amplitudes in the planarExpand
Conformal collider physics: energy and charge correlations
We study observables in a conformal field theory which are very closely related to the ones used to describe hadronic events at colliders. We focus on the correlation functions of the energiesExpand
On the stress tensor light-ray operator algebra
We study correlation functions involving generalized ANEC operators of the form $\int dx^- \left(x^-\right)^{n+2} T_{--}(\vec{x})$ in four dimensions. We compute two, three, and four-point functionsExpand
Abstract We resum distributions that are singular at partonic threshold (the elastic limit) in heavy quark production, in terms of logarithmic behavior in moment space. The method may be applied to aExpand
Spinning Gluons from the QCD Light-Ray OPE
We study the transverse spin structure of the squeezed limit of the three-point energy correlator, 〈E(~n1)E(~n2)E(~n3)〉. To describe its all orders perturbative behavior, we develop the light-rayExpand
Nonperturbative corrections in resummed cross sections
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. TheseExpand
Event shapes in N = 4 super-Yang-Mills theory
We study event shapes in N = 4 SYM describing the angular distribution of energy and R−charge in the final states created by the simplest half-BPS scalar operator. Applying the approach developed inExpand
