Simulation of semi-inclusive deep inelastic lepton scattering on a proton at energies of 20 – 100 GeV on the basis of the Generative-Adversarial Neural Network

St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2023
This paper continues a series of articles devoted to developing the capabilities of a deep inelastic lepton-proton scattering event generator based on the generative adversarial network (GAN).

Deeply learning deep inelastic scattering kinematics

European Physical Journal C: Particles and Fields, 2022
We study the use of deep learning techniques to reconstruct the kinematics of the neutral current deep inelastic scattering (DIS) process in electron–proton collisions. In particular, we use simulated data from the ZEUS experiment at the HERA accelerator

Unpolarized transverse momentum distributions from a global fit of Drell-Yan and semi-inclusive deep-inelastic scattering data

Journal of High Energy Physics, 2022
We present an extraction of unpolarized transverse-momentum-dependent parton distribution and fragmentation functions based on more than two thousand data points from several experiments for two different processes: semi-inclusive deep-inelastic ...

Transverse-energy-energy correlations in deep inelastic scattering

Journal of High Energy Physics, 2020
Event shape observables have been widely used for precision QCD studies at various lepton and hadron colliders. We present the most accurate calculation of the transverse-energy-energy correlation event shape variable in deep-inelastic scattering. In the

Semi-inclusive deep inelastic scattering in Wandzura-Wilczek-type approximation [PDF]

EPJ Web of Conferences, 2019
We present the complete cross-section for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering up to power-suppressed O(1/Q2) terms in the Wandzura–Wilczek-type approximation which consists in systematically assuming that q ...

Beam-helicity asymmetries for single-hadron production in semi-inclusive deep-inelastic scattering from unpolarized hydrogen and deuterium targets

Physics Letters B, 2019
A measurement of beam-helicity asymmetries for single-hadron production in deep-inelastic scattering is presented. Data from the scattering of 27.6 GeV electrons and positrons off gaseous hydrogen and deuterium targets were collected by the HERMES ...

Deep inelastic scattering on the quark-gluon plasma

Journal of High Energy Physics, 2021
We provide an interpretation of the structure functions of a thermal medium such as the quark-gluon plasma in terms of the scattering of an incoming electron on the medium via the exchange of a spacelike photon.

Single-inclusive jet production in electron–nucleon collisions through next-to-next-to-leading order in perturbative QCD

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,

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 ...
