Electroweak gauge boson parton distribution functions
Journal of High Energy Physics, 2018 Transverse and longitudinal electroweak gauge boson parton distribution functions (PDFs) are computed in terms of deep-inelastic scattering structure functions, following the recently developed method to determine the photon PDF. The calculation provides

NNLO Antenna Subtraction with One Hadronic Initial State [PDF]
, 2009 In this talk we present the extension of the antenna subtraction method to include initial states containing one hadron at NNLO. We sketch the requirements for the different necessary subtraction terms, and we explain how the antenna functions are ...

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

A Multiquark Approach to Excited Hadrons and Regge Trajectories
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 We propose a novel approach to construction of hadron spectroscopy. The case of light nonstrange mesons is considered. By assumption, all such mesons above 1 GeV appear due to creation of constituent quark‐antiquark pairs inside π or ρ(ω) mesons. These spin‐singlet or triplet pairs dictate the quantum numbers of formed resonance.

, 2001 Spin effects in exclusive and inclusive reactions provide an essential new dimension for testing QCD and unraveling hadron structure. Remarkable new experiments from SLAC, HERMES (DESY), and the Jefferson Laboratory present many challenges to theory ...

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 ...

Study of the sign change of the Sivers function from STAR collaboration W/Z production data
Journal of High Energy Physics, 2017 Recent data on the transverse single spin asymmetry A N measured by the STAR Collaboration for p ↑ p → W ± /Z 0 X reactions at RHIC allow the first investigation of the Sivers function in Drell-Yan processes and of its expected sign change with respect ...

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.
