Exclusive double quarkonium production and generalized TMDs of gluons

28 Feb 2018  ·  Bhattacharya Shohini, Metz Andreas, Ojha Vikash Kumar, Tsai Jeng-Yuan, Zhou Jian ·

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 ($\eta_c$ or $\eta_b$) in nucleon-nucleon collisions gives access to GTMDs of gluons...
