Title: Analytical Computation of Energy-Energy Correlation at Next-to-Leading Order in QCD

Abstract

Here, 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 provide the expansion of the EEC in the collinear and back-to-back regions through next-to-leading power, information which should aid resummation in these regions.

Collinear limit of the energy-energy correlator

Journal Article Dixon, Lance J. ; Moult, Ian ; Zhu, Hua Xing - Physical Review D

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 angle between the two detectors approaches zero, is of particular interest for describing the substructure of jets produced at hadron colliders as well as in e⁺e^– annihilation. We derive a factorization formula for the leading power asymptotic behavior in the collinear limit of a generic quantum field theory, which allows for the resummation of logarithmically enhanced terms to all orders by renormalization group evolution. The relevant anomalous dimensions are expressed in termsmore »« less

Challenges with large transverse momentum in semi-inclusive deeply inelastic scattering

Journal Article Gonzalez-Hernandez, J. O. ; Rogers, T. C. ; Sato, N. ; ... - Physical Review D

We survey the current phenomenological status of semi-inclusive deep inelastic scattering at moderate hard scales and in the limit of very large transverse momentum. As the transverse momentum becomes comparable to or larger than the overall hard scale, the differential cross sections should be calculable with fixed order pQCD methods, while small transverse momentum (TMD factorization) approximations should eventually break down. We find large disagreement between HERMES and COMPASS data and fixed order calculations done with modern parton densities, even in regions of kinematics where such calculations should be expected to be very accurate. Possible interpretations are suggested.

Simplicity from recoil: the three-loop soft function and factorization for the energy-energy correlation

Journal Article Moult, Ian ; Zhu, Hua Xing - Journal of High Energy Physics (Online)

We derive an operator based factorization theorem for the energy-energy correlation (EEC) observable in the back-to-back region, allowing the cross section to be written as a convolution of hard, jet and soft functions. We prove the equivalence of the soft functions for the EEC and color singlet transverse-momentum resummation to all-loop order, and give their analytic result to three-loops. Large logarithms appearing in the perturbative expansion of the EEC can be resummed to all orders using renormalization group evolution. We give analytic results for all required anomalous dimensions to three-loop order, providing the first example of a transverse-momentum (recoil) sensitivemore »« less

One-loop matching and next-to-next-to-leading log resummation for all partonic 2{yields}2 processes in QCD

Journal Article Kelley, Randall ; Schwartz, Matthew D - Physical Review. D, Particles Fields

The Wilson coefficients for all 4-parton operators which arise in matching QCD to soft-collinear effective theory (SCET) are computed at 1-loop. Any dijet observable calculated in SCET beyond leading order will require these results. The Wilson coefficients are separated by spin and color, although most applications will involve only the spin-averaged hard functions. The anomalous dimensions for the Wilson coefficients are given to 2-loop order, and the renormalization group equations are solved explicitly. This will allow for analytical resummation of dijet observables to next-to-next-to-leading logarithmic accuracy. For each channel, there is a natural basis in which the evolution is diagonalmore »« less

Next-to-leading order QCD jet production with parton showers and hadronization

Journal Article Kraemer, Michael ; Mrenna, Stephen ; Soper, Davison E ; ... - Physical Review. D, Particles Fields

We report on a method for matching the next-to-leading order calculation of QCD jet production in e{sup +}e{sup -} annihilation with a Monte Carlo parton shower event generator (MC) to produce realistic final states. The final result is accurate to next-to-leading order (NLO) for infrared-safe one-scale quantities, such as the Durham 3-jet fraction y{sub 3}, and agrees well with parton shower results for multiscale quantities, such as the jet mass distribution in 3-jet events. For our numerical results, the NLO calculation is matched to the event generator Pythia, though the method is more general. We compare one-scale and multiscale quantitiesmore »« less
