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

Observable jets in deep inelastic scattering as a probe of small x dynamics [PDF]

, 1997
The observation of the underlying small x dynamics arising from the resummation of large terms in In 1/x QCD descriptions of the gluon distribution have been searched for ill deep inelastic scattering experiments at the electron proton collider HERA ...

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.

Measurement of the hadronic photon structure function F_{2}^{γ} at LEP2 [PDF]

, 2002
The hadronic structure function of the photon F_{2}^{γ} (x, Q²) is measured as a function of Bjorken x and of the photon virtuality Q² using deep-inelastic scattering data taken by the OPAL detector at LEP at e⁺e⁻ centre-of-mass energies from 183 to 209 ...

HERWIG 6: an event generator for Hadron emission reactions with interfering gluons (including supersymmetric processes) [PDF]

, 2000
HERWIG is a general-purpose Monte Carlo event generator, which includes the simulation of hard lepton-lepton, lepton-hadron and hadron-hadron scattering and soft hadron-hadron collisions in one package. It uses the parton-shower approach for initial- and

Studies of final states in small x deep inelastic scattering [PDF]

, 1997
We investigate the possibility of identifying In(l/x) dynamics from studies of the final state in electron - proton deep inelastic scattering (DIS) in the small x region of the HERA collider at DESY.

Vector meson production at low x from gauge/gravity duality

, 2013
We use gauge/gravity duality to study vector meson (J/?, ? 0 , ?, ?) production in electron-proton scattering, in the limit of high center of mass energy at fixed momentum transfer, corresponding to the limit of low Bjorken x, where the process is ...

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
