Universality of Quark and Gluon TMD Correlators
M. G. A. Buffing, P. J. Mulders, A. Mukherjee
Transverse Momentum Dependent (TMD) parton distribution functions (PDFs), in short referred to as TMDs, also take into account the transverse momentum (pT) of the partons. Just as…
Color entanglement for azimuthal asymmetries in the Drell-Yan process
M. G. A. Buffing, P. J. Mulders
In the resummation of collinear gluons emitted together with active partons from the hadrons in the Drell-Yan process (DY) effects of color entanglement become important when the t…
Linear polarization of gluons and photons in unpolarized collider experiments
Cristian Pisano, Daniel Boer, Stanley J. Brodsky +2
We study azimuthal asymmetries in heavy quark pair production in unpolarized electron-proton and proton-proton collisions, where the asymmetries originate from the linear polarizat…
Universality of TMD distribution functions
M. G. A. Buffing, A. Mukherjee, P. J. Mulders
We introduce transverse momentum dependent parton distribution functions (TMDs) for gluons with definite rank. The rank refers to the azimuthal dependence corresponding to the tens…
Generalized Universality of Definite Rank Gluon Transverse Momentum Dependent Correlators
M. G. A. Buffing, A. Mukherjee, P. J. Mulders
Transverse momentum dependent (TMD) parton correlators describing the partonic structure of hadrons contain gauge links, required by color gauge invariance. The required gauge link…
