Rapidity-only TMD factorization at one loop
Journal of High Energy Physics, 2023 Typically, a production of a particle with a small transverse momentum in hadron-hadron collisions is described by CSS-based TMD factorization at moderate Bjorken x B ~ 1 and by k T -factorization at small x B . A uniform description valid for all x B is

Quark and gluon helicity evolution at small x: revised and updated
Journal of High Energy Physics, 2022 We revisit the problem of small Bjorken-x evolution of the gluon and flavor-singlet quark helicity distributions in the shock wave (s-channel) formalism.

Gluon-mediated inclusive Deep Inelastic Scattering from Regge to Bjorken kinematics
Journal of High Energy Physics, 2022 We revisit high energy factorization for gluon mediated inclusive Deep Inelastic Scattering (DIS) for which we propose a new semi-classical approach that accounts systematically for the longitudinal extent of the target in contrast with the shockwave ...

Machine learning of log-likelihood functions in global analysis of parton distributions
Journal of High Energy Physics, 2022 Modern analysis on parton distribution functions (PDFs) requires calculations of the log-likelihood functions from thousands of experimental data points, and scans of multi-dimensional parameter space with tens of degrees of freedom.

New tool for kinematic regime estimation in semi-inclusive deep-inelastic scattering
Journal of High Energy Physics, 2022 We introduce a new phenomenological tool based on momentum region indicators to guide the analysis and interpretation of semi-inclusive deep-inelastic scattering measurements.

LHC soft physics and TMD gluon density at low x [PDF]
, 2013 We study the unintegrated, or transverse momentum dependent (TMD) gluon distribution obtained from the best description of the LHC data on the inclusive spectra of hadrons produced in the mid-rapidity region and low transverse momenta at starting scale ...

Dijet azimuthal correlations in p-p and p-Pb collisions at forward LHC calorimeters
Journal of High Energy Physics, 2022 We present a state-of-the-art computation for the production of dijets in proton-proton and proton-lead collisions at the LHC, in forward rapidity domains covered by the ATLAS calorimeter and the planned FoCal extension of the ALICE detector.

Transverse Momentum in Semi-Inclusive Polarized Deep Inelastic Scattering and the Spin-Flavor Structure of the Proton [PDF]
, 2002 The non-valence spin-flavor structure of the nucleon extracted from semi-inclusive measurements of polarized deep inelastic scattering depends strongly on the transverse momentum of the detected hadrons which are used to determine the individual ...

NLO JIMWLK evolution with massive quarks
Journal of High Energy Physics, 2022 NLO evolution of the Jalilian-Marian-Iancu-McLerran-Weigert-Leonidov-Kovner (JIMWLK) equation with massless quarks was derived a few years ago. We make a step further to compute the evolution kernels focusing on the effects due to finite quark masses. To
