The Conformal Template and New Perspectives for Quantum Chromodynamics [PDF]

, 2007
Conformal symmetry provides a systematic approximation to QCD in both its perturbative and nonperturbative domains. One can use the AdS/CFT correspondence between Anti-de Sitter space and conformal gauge theories to obtain an analytically tractable ...

Systematic analysis of double-scale evolution

Journal of High Energy Physics, 2018
Often the factorization of differential cross sections results in the definition of fundamental hadronic functions/distributions which have a double-scale evolution, as provided by a pair of coupled equations.

Applications of Light-Front QCD [PDF]

, 2004
Light-front Fock state wavefunctions encode the bound state properties of hadrons in terms of their quark and gluon degrees of freedom at the amplitude level.

Diffractive Phenomena and Shadowing in Deep-Inelastic Scattering

, 1997
Shadowing effects in deep-inelastic lepton-nucleus scattering probe the mass spectrum of diffractive leptoproduction from individual nucleons. We explore this relationship using current experimental information on both processes.

The triple-pomeron regime and the structure function of the pomeron in the diffractive deep inelastic scattering at very small x

, 1993
Misprints and numerical coefficients corrected, a bit of phenomenology and one figure added. The case for the linear evolution of the unitarized structure functions made stronger.Comment: KFA-IKP(Th)-1993-17, Landau-16/93, 46 pages, 14 figures upon ...

Ultrahigh-Energy Neutrino-Nucleon Cross Sections and Perturbative Unitarity [PDF]

, 2001
Unitarity relates the total cross section for neutrino-nucleon scattering to the neutrino-nucleon forward scattering amplitude. Assuming the validity of the perturbative expansion of the forward amplitude in the {\em weak} coupling constant, we derive a ...

QCD evolution of the gluon Sivers function in heavy flavor dijet production at the Electron-Ion Collider

Journal of High Energy Physics, 2021
Using Soft-Collinear Effective Theory, we develop the transverse-momentum-dependent factorization formalism for heavy flavor dijet production in polarized-proton-electron collisions. We consider heavy flavor mass corrections in the collinear-soft and jet

Progress in the Determination of the Partonic Structure of the Proton

, 2013
We review the current state of the art in the determination of the parton substructure of the nucleon, as expressed in terms of parton distribution functions (PDFs), and probed in high-energy lepton-hadron and hadron-hadron collisions, and we assess ...

Deep inelastic scattering at HERA and the BFKL pomeron

Novel Aspects of QCD in Leptoproduction

, 2004
I review several topics in electroproduction which test fundamental aspects of QCD. These include the role of final-state interactions in producing diffractive leptoproduction processes, the shadowing of nuclear structure functions, and target-spin ...
