Abstract

We discuss inclusive production of pairs of J/ψ quarkonia. Both leading-order single parton (box) contribution and double-parton contributions are included. In addition we discuss a contribution of higher-order two-gluon exchange and a feed down from double χ_c production. The second two contributions are important for large rapidity distance between the two J/ψ mesons and for relatively large cut-offs on quarkonia transverse momenta. A relation to current experiments is discussed.
