Physics Letters B, 2016 We compute the O(α2αs2) perturbative corrections to inclusive jet production in electron–nucleon collisions. This process is of particular interest to the physics program of a future Electron Ion Collider (EIC). We include all relevant partonic processes,

The Drell-Yan process with pions and polarized nucleons
Journal of High Energy Physics, 2021 The Drell-Yan process provides important information on the internal struc- ture of hadrons including transverse momentum dependent parton distribution functions (TMDs).

Quark-sector Lorentz violation in Z-boson production
Journal of High Energy Physics, 2021 Quark-sector Lorentz violation is studied in the context of Drell-Yan dilepton production including effects from Z-boson exchange. We show the chiral nature of the weak interactions enables parity-violating and spin-dependent effects to be studied using ...

DEEP INELASTIC SCATTERING AT HERA [PDF]
International Journal of Modern Physics A, 1998 Results from the H1 and ZEUS experiments at HERA on deep inelastic scattering are reviewed. The data lead to a consistent picture of a steep rise in the F2 structure function and in the gluon density within the proton. Important new information on the partonic structure of diffraction is emerging from H1 and ZEUS.

Lorentz violation and deep inelastic scattering
Physics Letters B, 2017 The effects of quark-sector Lorentz violation on deep inelastic electron–proton scattering are studied. We show that existing data can be used to establish first constraints on numerous coefficients for Lorentz violation in the quark sector at an ...

Kinematic distributions of the η c leptoproduction in association with light hadrons
Journal of High Energy Physics, 2021 The η c meson leptoproduction is calculated within the nonrelativistic QCD framework for the first time. It is found that the colour-singlet channel, although suppressed by a factor of α s relative to the colour-octet ones, provides important ...

Deep Inelastic Scattering on Ultracold Gases
Physical Review X, 2017 We discuss Bragg scattering on both Bose and Fermi gases with strong short-range interactions in the deep inelastic regime of large wave vector transfer q, where the dynamic structure factor is dominated by a resonance near the free-particle energy ℏω=ϵ_{

Soft corrections to inclusive deep-inelastic scattering at four loops and beyond
Journal of High Energy Physics, 2020 We study the threshold corrections for inclusive deep-inelastic scattering (DIS) and their all-order resummation. Using recent results for the QCD form factor, related anomalous dimensions and Mellin moments of DIS structure functions at four loops we ...

Rise of the DIS structure function F L at small x caused by double-logarithmic corrections
Journal of High Energy Physics, 2021 We present calculation of F L in the double-logarithmic approximation (DLA) and demonstrate that the synergic effect of the factor 1/x from the α s 2 $$ {\alpha}_s^2 $$ -order and the steep x-dependence of the totally resummed double logarithmic ...

A new approach to semi-inclusive deep-inelastic scattering with QED and QCD factorization
Journal of High Energy Physics, 2021 We present the details of a new factorized approach to semi-inclusive deep-inelastic scattering which treats QED and QCD radiation on equal footing, and provides a systematically improvable approximation to the extraction of transverse momentum dependent
