, 2004 Parton distributions, α(χ,μ(^₂) are essential ingredients for almost all theoretical calculations at hadron colliders. They give the number densities of the colliding par- tons (quarks and gluons) inside their parent hadrons at a given momentum fraction ...

Angularity in DIS at next-to-next-to-leading log accuracy
Journal of High Energy Physics, 2021 Angularity is a class of event-shape observables that can be measured in deep-inelastic scattering. With its continuous parameter a one can interpolate angularity between thrust and broadening and further access beyond the region.

A Guide to Light‐Cone PDFs from Lattice QCD: An Overview of Approaches, Techniques, and Results
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 Within the theory of Quantum Chromodynamics (QCD), the rich structure of hadrons can be quantitatively characterized, among others, using a basis of universal nonperturbative functions: parton distribution functions (PDFs), generalized parton distributions (GPDs), transverse momentum dependent parton distributions (TMDs), and distribution amplitudes ...

Measurement of the neutral current reaction at high Q2 in the H1 experiment at HERA II [PDF]
, 2012 This thesis presents inclusive ep double and single differential cross section measurements for neutral current deep inelastic scattering of longitudinally polarized leptons on protons as a function of the negative four-momentum transfer squared Q2 and ...

Journal of High Energy Physics, 2019 In this paper, we study the azimuthal asymmetry in the J/𝜓 leptoproduction in unpolarized ep collisions. There are two independent azimuthal asymmetry modulations, namely cos(𝜓) and cos (2 𝜓), where 𝜓 is the azimuthal angle of the lepton scattering plane

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 The twist‐3 collinear factorization framework has drawn much attention in recent decades as a successful approach in describing the data for single spin asymmetries (SSAs). Many SSAs data have been experimentally accumulated in a variety of energies since the first measurement was done in the late 1970s and it is expected that the future experiments ...

Proton structure from deep inelastic and diffractive scattering [PDF]
, 1996 We investigate various aspects of the proton structure in this thesis. The first addresses the distribution of the proton spin among its constituents, quarks and gluons.

Polarized parton distributions from charged-current deep-inelastic scattering and future neutrino factories [PDF]
, 2001 We discuss the determination of polarized parton distributions from charged-current deep-inelastic scattering experiments. We summarize the next-to-leading order treatment of charged-current polarized structure functions, their relation to polarized ...

Determining the helicity structure of the nucleon at the Electron Ion Collider in China
Journal of High Energy Physics, 2021 Understanding how sea quarks behave inside a nucleon is one of the most important physics goals of the proposed Electron-Ion Collider in China (EicC), which is designed to have a 3.5 GeV polarized electron beam (80% polarization) colliding with a 20 GeV ...
