Description
We present a extensive phenomenological study of Drell-Yan and heavy quarkonia production at LHC and RHIC energies within the color dipole formalism. Using Color-Singlet model (CSM) we calculate several different observables including quarkonia pT spectra and rapidity/azimuth difference between J/psi or Y and leading hadron in p-p and p-A collisions. Moreover, the gauge boson (Z0, W±) production in association with hadron that fragments from the incoming quark is calculated, and then applied to study gauge boson-hadron correlations at LHC energies. This provides a complementary analysis tool to prompt-photon–hadron and hadron-hadron correlations within the color dipole formalism.
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. All suggested variables have a strong potential for better constraining CSM contribution to the J/psi and Y production at RHIC and LHC.
