The twist-three distribution eq(x,k⊥) in a light-front model

Physics Letters B, 2019
We discuss the twist-three, unpolarized, chiral-odd, transverse momentum dependent parton distribution (TMD) eq(x,k⊥) within a light-front model. We review a model-independent decomposition of this TMD, which follows from the QCD equations of motion and ...

Monte Carlo Generators for Studies of the 3D Structure of the Nucleon

EPJ Web of Conferences, 2015
Extraction of transverse momentum and space distributions of partons from measurements of spin and azimuthal asymmetries requires development of a self consistent analysis framework, accounting for evolution effects, and allowing control of systematic ...

Transverse structure of the proton beyond leading twist: A light-front Hamiltonian approach

Physics Letters B
Within the Basis Light-Front Quantization framework, we systematically investigate the subleading twist (twist-3) transverse-momentum-dependent parton distribution functions (TMDs) of the proton beyond the Wandzura-Wilczek (WW) approximation.

Multidimensional, High Precision Measurements of Beam Single Spin Asymmetries in Semi-inclusive π+ Electroproduction off Protons in the Valence Region [PDF]

, 2022
High precision measurements of the polarized electron beam-spin asymmetry in semi-inclusive deep inelastic scattering (SIDIS) from the proton have been performed using a 10.6 GeV incident electron beam and the CLAS12 spectrometer at Jefferson Lab.

Probing the Quark-Gluon Plasma with a New Fermionic Correlator [PDF]

Physical Review Letters, 1999
We present the first measurement of a new correlation function of Fermion bilinears in finite temperature QCD with and without dynamical quarks in a quantum number channel in which non-trivial correlations are known to be present for purely gluonic operators.

A coherent view of the quark-gluon plasma from energy correlators

Journal of High Energy Physics, 2023
AbstractThe ability to measure detailed aspects of the substructure of high-energy jets traversing the quark-gluon plasma (QGP) has provided a new window into its internal dynamics. However, drawing robust conclusions from traditional jet substructure observables has been difficult.

Nonperturbative quark, gluon, and meson correlators of unquenched QCD [PDF]

Physical Review D, 2018
We present non-perturbative first-principle results for quark-, gluon- and meson $1$PI correlation functions of two-flavour Landau-gauge QCD in the vacuum. These correlation functions carry the full information about the theory. They are obtained by solving their Functional Renormalisation Group equations in a systematic vertex expansion, aiming at ...

ZZ production at nNNLO+PS with MiNNLOPS

Journal of High Energy Physics, 2022
We consider ZZ production in hadronic collisions and present state-of-the-art predictions in QCD perturbation theory matched to parton showers. Next-to-next-to-leading order corrections to the quark-initiated channel are combined with parton showers ...

Parton energy loss and the generalized jet transport coefficient [PDF]

, 2021
We revisit radiative parton energy loss in deeply inelastic scattering (DIS) off a large nucleus within the perturbative QCD approach. We calculate the gluon radiation spectra induced by double parton scattering in DIS without collinear expansion in the ...
