  We study the production of an electroweak boson in association with jets, in
processes where the jet with the highest transverse momentum is identified as
quark-initiated. The quark/gluon tagging procedure is realised by a cut on a
jet angularity and it is therefore theoretically well-defined and exhibits
infrared and collinear safety. In this context, exploiting resummed
perturbation theory, we are able to provide theoretical predictions for
transverse momentum distributions at a well-defined and, in principle,
systematically improvable accuracy. In particular, tagging the leading jet as
quark-initiated allows us to enhance the initial-state gluon contribution.
Thus, these novel transverse momentum distributions are potentially interesting
observables to probe the gluonic degrees of freedom of the colliding protons.
