Infrared behaviour and renormalization scheme invariance of QCD observables [PDF]

open access: yes, 2006
In this thesis we study the infrared (IR) behaviour of QCD observables, and solutions to the problem of renormalization scheme dependence. We investigate the IR behaviour of all-orders leading-b renormalon resummations for certain Euclidean observables ...

Deep-inelastic scattering, partons and strong interaction ideas [PDF]

open access: yes, 1973
The quark-parton model as applied to deep-inelastic lepton-hadron scattering is used as a laboratory model for the study of ideas encountered in strong interaction physics. First, two-component duality constraints are imposed on single-particle inclusive

Semi-inclusive back-to-back production of a hadron pair and a single hadron in e + e − annihilation

open access: yesJournal of High Energy Physics, 2018
Inclusive hadron production in e + e − annihilation has long been used to study both single hadron fragmentation functions (FF) and dihadron fragmentation functions (DiFF).

Matching of fracture functions for SIDIS in target fragmentation region

open access: yesJournal of High Energy Physics, 2021
In the target fragmentation region of Semi-Inclusive Deep Inelastic Scattering, the diffractively produced hadron has small transverse momentum. If it is at order of ΛQCD, it prevents to make predictions with the standard collinear factorization. However,

Systematic analysis of double-scale evolution

open access: yesJournal 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.

Quark mass effects in deeply inelastic scattering [PDF]

open access: yes, 1996
We argue that the difference between the structure functions corresponding to deep inelastic scattering with and without heavy quarks in the current fragmentation region scales at high Q and fixed (low ...

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

open access: yesJournal 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

General approach to deep inelastic scattering [PDF]

open access: yes, 1976
Due to preliminary indications of a possible scaling violation it is interesting to clarify which of the parton light-cone results are indeed the consequences of a more general scheme.

Exclusive J/ψ and ψ(2S) production inppcollisions at √s=7 TeV [PDF]

open access: yes, 2013
Exclusive J/ψ and ψ (2S) vector meson production has been observed in the dimuon channel using the LHCb detector. The cross-section times branching fractions to two muons with pseudorapidities between 2.0 and 4.5 are measured to be σpp→J/ψ (→μ +μ −)

Nucleon Models of Deep Inelastic Scattering [PDF]

open access: yes, 1992
Nucleon models should describe both deep inelastic scattering and low energy phenomenology. We review some recent calculations of valence quark distributions.
