摘要：

We show that the diffractive forward production of two quarkonia, especially the chi(cJ) and eta(c) states, in proton-proton or proton-ion collisions can access the Weizsacker-Williams gluon Wigner distribution of the proton. We use the hybrid factorization approach where the collinear, double gluon PDF is applied for one of the protons and the k(T)-dependent(Wigner or GTMD) distribution for the other. The production of quarkonia is treated in the NRQCD framework. A particularly concise formula is obtained for double chi(J=1) production.
