Abstract
Being the “mother distributions” of all types of two-parton correlation functions, generalized transverse momentum dependent parton distributions (GTMDs) have attracted a lot of attention over the last years. We argue that exclusive double production of pseudoscalar quarkonia (η<sub>c</sub> or η<sub>b</sub>) in nucleon-nucleon collisions gives access to GTMDs of gluons.
