Two-loop splitting in double parton distributions: the colour non-singlet case
Journal of High Energy Physics, 2021 At small inter-parton distances, double parton distributions receive their dominant contribution from the splitting of a single parton. We compute this mechanism at next-to-leading order in perturbation theory for all colour configurations of the ...

ρ meson GPDs and IPDs with a light-front constituent quark model [PDF]
EPJ Web of Conferences, 2019 We investigate the ρ meson unpolarized Generalized Parton Distributions based on a Light-Front Constituent Quark Model. Moreover, by employing a Gaussian form wave packet, we apply the obtained generalized parton distributions to get the Impact Parameter

Valence and sea parton correlations in double parton scattering from data
Journal of High Energy Physics, 2023 The effective cross section of double parton scattering in proton collisions has been measured by many experiments with rather different results. Motivated by this fact, we assumed that the parton correlations in the transverse plane are different ...

Calculations with off-shell matrix elements, TMD parton densities and TMD parton showers
European Physical Journal C: Particles and Fields, 2018 A new calculation using off-shell matrix elements with TMD parton densities supplemented with a newly developed initial state TMD parton shower is described.

Anisotropic parton escape is the dominant source of azimuthal anisotropy in transport models
Physics Letters B, 2016 We trace the development of azimuthal anisotropy (vn, n=2,3) via parton–parton collision history in two transport models. The parton vn is studied as a function of the number of collisions of each parton in Au + Au and d+Au collisions at sNN=200 GeV.

Double parton distributions out of bounds in colour space
European Physical Journal C: Particles and Fields, 2021 We investigate the positivity of double parton distributions with a non-trivial dependence on the parton colour. It turns out that positivity is not preserved by leading-order evolution from lower to higher scales, in contrast to the case in which parton

Collinear matching for next-to-leading power transverse-momentum distributions
Physics Letters B, 2023 Phenomenological studies of transverse momentum dependent (TMD) parton distributions rely on the expansion in small values of the transverse separation of fields, where TMD parton distributions match onto collinear parton distribution functions.

Double parton distributions in the pion from lattice QCD
Journal of High Energy Physics, 2021 We perform a lattice study of double parton distributions in the pion, using the relationship between their Mellin moments and pion matrix elements of two local currents. A good statistical signal is obtained for almost all relevant Wick contractions. We
