Description

We discuss possible experimental tests of the Color-Singlet model (CSM) in associated J/psi or Y plus leading hadron production in pp collisions at RHIC and LHC energies. Using color dipole approach we calculate several different observables of leading hadron and rapidity/azimuth difference between produced J/psi or Y and the leading hadron in the CSM approach. As a very promising measurement we suggest to study correlations between forward high-pT pion and J/psi or Y produced at mid-rapidity at RHIC energies. Such forward-midrapidity correlations test higher order pQCD in pp collisions at modest energies and also may shed more light on forward high-pT particle production in pA collisions. All suggested variables have a strong potential for better constraining CSM contribution to the J/psi and Y production at RHIC and LHC.
