Query: Momentum Imbalance Observables as a Probe of Gluon TMDs   The unpolarized and linearly polarized gluon TMDs can be directly probed in
heavy quark and jet pair production in unpolarized electron-proton collisions
by looking at observables, like transverse momentum distributions and azimuthal
asymmetries, depending on the momentum imbalance of the pair. Analytical
expressions are presented for these observables and for analogous ones in Higgs
plus jet and quarkonium plus photon production in unpolarized proton-proton
scattering experiments. It is shown how the proposed measurements, to be
performed at a future EIC and at the LHC, could provide important information
on the size and shape of gluon TMDs, as well as on other fundamental properties
such as their process and energy scale dependences.
