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 ...

Quark-gluon correlations and Color Polarizabilities [PDF]
AIP Conference Proceedings, 2006 We discuss the present status of the twist‐3 matrix element in the spin srtructure of the nucleon and describe two proposed experiments that will improve on the precision of the present measurements of the twist‐3 and twist‐4 matrix elements for both the proton and the neutron and consequently will improve on our knowledge of the “color ...

QCD Evolution of Nuclear Quark-Gluon Correlation Function [PDF]
International Journal of Modern Physics: Conference Series, 2015 We summarize the results on the next-to-leading order (NLO) calculations of transverse momentum broadening in semi-inclusive deeply inelastic e + A scattering (SIDIS) and Drell-Yan dilepton production (DY) in p + A collisions. The corresponding transverse momentum weighted differential cross sections are shown to factorize at NLO.

Squeezed and Entangled Gluon States in QCD Jet
EPJ Web of Conferences, 2016 Theoretical justification for the occurrence of multimode squeezed and entan-gled colour states in QCD is given. We show that gluon entangled states which are closely related with corresponding squeezed states can appear by the four-gluon self ...

T-odd quark–gluon–quark correlation function in the diquark model [PDF]
Physics Letters B, 2012 We study the transverse momentum dependent quark-gluon-quark correlation function. Using a spectator diquark model, we calculate the eight time-reversal-odd interaction-dependent twist-3 quark distributions appearing in the decomposition of the transverse momentum dependent quark-gluon-quark correlator.

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 ...

Measurement of the top quark charge in pp collisions at s√=7 TeV with the ATLAS detector [PDF]
, 2013 A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb−1 of data at a centre-of-mass energy of 7 TeV. In units of the elementary electric charge, the top quark charge is determined

Quantum Optics Properties of QCD Vacuum
EPJ Web of Conferences, 2017 Theoretical justification of the occurrence of multimode squeezed and entangled colour states in QCD is given. We show that gluon entangled states which are closely related with corresponding squeezed states can appear by the four-gluon self-interaction.

Journal of High Energy Physics, 2018 In this paper, we study the spatial correlations among quarks and antiquarks produced at mid-rapidity by gluon pair production in the color glass condensate framework. This paper is the first part of a series in which we calculate a complete set of quark/

Interplay between core and corona from small to large systems [PDF]
EPJ Web of Conferences, 2023 We present new results in p+p and Pb+Pb collisions at the LHC energies from the updated dynamical core–corona initialization framework (DCCI2). The fractions of final hadron yields originating from equilibrated and non-equilibrated components are ...
