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).

Mapping the kinematical regimes of semi-inclusive deep inelastic scattering
Journal of High Energy Physics, 2019 We construct a language for identifying kinematical regions of transversely differential semi-inclusive deep inelastic scattering (SIDIS) cross sections with particular underlying partonic pictures, especially in the regions of moderate to low Q where ...

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

Small $x$ physics in deep inelastic lepton scattering [PDF]
Acta Phys.Polon.B26:1933-1960,1995, 1995 The perturbative QCD predictions concerning deep inelastic scattering at low $x$ are summarized. The theoretical framework based on the leading log $1/x$ resummation and $k_t$ factorization theorem is described. The role of studying final states in deep inelastic scattering for revealing the details of the underlying dynamics at low $x$ is emphasised ...

The high-energy limit of inclusive and diffractive deep inelastic scattering in QCD [PDF]
, 2006 Following recent progresses in the understanding of high-energy scattering in QCD, we derive the first phenomenological consequences of Pomeron loops, in the context of both inclusive and diffractive deep inelastic scattering. In particular, we discuss diffusive scaling, a new scaling law that emerges for sufficiently high energies and up to very large

O(α) QED Corrections to Polarized Elastic $μe$ and Deep Inelastic l N Scattering [PDF]
arXiv, 1997 Two computer codes relevant for the description of deep inelastic scattering off polarized targets are discussed. The code ${\mu}$ela deals with radiative corrections to elastic $\mu e$ scattering, one method applied for muon beam polarimetry. The code HECTOR allows to calculate both the radiative corrections for unpolarized and polarized deep ...

Instanton-induced particle production in deep inelastic scattering [PDF]
arXiv, 1993 I discuss the instanton-induced contributions to the coefficient functions in front of parton densities. They correspond to the spherically symmetric particle production at the level of $10^{-2}-10^{-5}$ of the total cross section of deep inelastic scattering from the parton.

New physics opportunities for long-lived particles at electron-proton colliders
Journal of High Energy Physics, 2018 Future electron-proton collider proposals like the LHeC or the FCC-eh can supply ab−1 of collisions with a center-of-mass energy in the TeV range, while maintaining a clean experimental environment more commonly associated with lepton colliders. We point
