Towards parton distribution functions with small-x resummation: HELL 2.0

Journal of High Energy Physics, 2017
In global fits of parton distribution functions (PDFs) a large fraction of data points, mostly from the HERA collider, lies in a region of x and Q 2 that is sensitive to small-x logarithmic enhancements.

Saturation effects in SIDIS at very forward rapidities

Journal of High Energy Physics, 2021
Using the dipole picture for electron-nucleus deep inelastic scattering at small Bjorken x, we study the effects of gluon saturation in the nuclear target on the cross-section for SIDIS (single inclusive hadron, or jet, production).

Low-x improved TMD approach to the lepto- and hadroproduction of a heavy-quark pair

Journal of High Energy Physics, 2021
We study the lepto- and hadroproduction of a heavy-quark pair in the ITMD factorization framework for dilute-dense collisions. Due to the presence of a nonzero quark mass and/or nonzero photon virtuality, new contributions appear compared to the cases of

Neutron Parton Structure And The Light-Front Spectral Function Of 3He

, 2017
Semi-inclusive deep inelastic electron scattering off polarized 3He is studied in a non-relativistic framework, using a distorted spin-dependent spectral function for 3He to take care of the final state interaction between the observed pion and the ...

Quarkonium production in deep-inelastic scattering [PDF]

, 2002
We discuss the inclusive production of J/psi mesons in deep-inelastic scattering (DIS) via the electromagnetic, weak neutral, and charged currents within the factorization formalism of nonrelativistic quantum chromodynamics.

Extraction of unpolarized quark transverse momentum dependent parton distributions from Drell-Yan/Z-boson production

Journal of High Energy Physics, 2019
We present the extraction of unpolarized quark transverse momentum dependent parton distribution functions (TMDPDFs) and the non-perturbative part of TMD evolution kernel from the global analysis of Drell-Yan and Z-boson production data.

Summary of Working Group I: Hadron Structure [PDF]

, 1997
A summary is given on the main aspects which were discussed by the working group. They include new results on the deep inelastic scattering structure functions $F_2, xF_3, F_L$ and $F_2^{c\bar{c}}$ and their parametrizations, the measurement of the gluon

What is novel in quantum transport for mesoscopics?

, 2005
The understanding of mesoscopic transport has now attained an ultimate simplicity. Indeed, orthodox quantum kinetics would seem to say little about mesoscopics that has not been revealed - nearly effortlessly - by more popular means. Such is far from the

Saturation model of DIS: an update

Journal of High Energy Physics, 2018
We present the results of new fits to the recently extracted data on F 2 at low x with the GBW saturation model and its modification to cover high values of Q 2. We find that the model stands the test of time and gives a good description of the data with

BFKL evolution and universal structure function at very small $x$

, 1994
The Balitskii-Fadin-Kuraev-Lipatov (BFKL) and the Gribov-Lipatov- Dokshitzer-Altarelli-Parisi (GLDAP) evolution equations for the diffractive deep inelastic scattering at ${1\over x} \gg 1$ are shown to have a common solution in the weak coupling limit: $
