Abstract
We present the calculation for single-inclusive jet production in (longitudinally) polarized deep-inelastic lepton-nucleon scattering at next-to-next-to leading order (NNLO) accuracy, based on the Projection-to-Born method. As a necessary ingredient to achieve the NNLO results, we also introduce the next-to-leading-order (NLO) calculation for the production of di-jets in polarized DIS. Our di-jet calculation is based on an extension of the dipole subtraction method to account for polarized initial-state partons. We analyze the phenomenological consequences of higher order QCD corrections for the Electron-Ion Collider kinematics.
Highlights
Much progress has been made in our understanding of the structure of hadrons over the last decades, both from the theoretical and the experimental sides
The spin content of the proton can be codified in terms of the polarized parton distributions of quarks and gluons, which can be experimentally probed in high energy collisions processes with polarized nucleons
In this paper we present the NLO calculation for dijet production in polarized and unpolarized lepton-nucleon deep-inelastic scattering (DIS), based on an extension of the Catani-Seymour dipole subtraction method [17] to account for polarized initial particles
Summary
Much progress has been made in our understanding of the structure of hadrons over the last decades, both from the theoretical and the experimental sides. In this paper we present the NLO calculation for dijet production in polarized and unpolarized lepton-nucleon DIS, based on an extension of the Catani-Seymour dipole subtraction method [17] to account for polarized initial particles. We analyze the perturbative stability of the higher order corrections to the cross section and asymmetries, as well as the contributions from the different partons to the NNLO corrections. Both the NLO single- and dijet, as well as the NNLO single-jet calculations are implemented in our code POLDIS [20].
