Constraining the double gluon distribution by the single gluon distribution

open access: yesPhysics Letters B, 2015
We show how to consistently construct initial conditions for the QCD evolution equations for double parton distribution functions in the pure gluon case.

Investigating the topology dependence of quark and gluon jets

open access: yesJournal of High Energy Physics, 2019
As most target final states for searches and measurements at the Large Hadron Collider have a particular quark/gluon composition, tools for distinguishing quark- from gluon-initiated jets can be very powerful.

The gluon form factor to higher orders: Gluon-gluon annihilation at small Qt

open access: yesPhysics Letters B, 1988
Abstract We study the region of small transverse momenta in the dynamics of the gluon-gluon annihilation channel. This is done by evaluating the gluon form factor at the single non-leading infrared and collinear logarithmic accuracy to all orders in α s . An explicit expression for the gluon form factor is obtained.

Transverse-momentum-dependent gluon distributions of proton within basis light-front quantization

open access: yesPhysics Letters B
Gluon transverse-momentum dependent distributions (TMDs) are very important for revealing the internal structure of the proton. They correspond to a variety of experiments and are among the major tasks of the future electron-ion colliders. In this paper,

Angular dependence in transverse momentum dependent diffractive parton distributions at small-x

open access: yesPhysics Letters B
We discuss the angular dependence of the recently proposed transverse momentum dependent quark and gluon diffractive parton distributions at small-x. We introduce the diffractive versions of the Sivers function and the elliptic gluon Wigner distribution ...
