Description
We present evidence of associated vector boson+prompt J/psi production
and measure its production rate. This is a key observable to further
the understanding of quarkonium production mechanisms. We estimate
the relative contributions to the signal from single and double
parton scattering (DPS) and discuss possible implications of this
novel final state for study of multiple parton interactions. We
also review the cross-section measurement of double-J/psi production,
separating the prompt-prompt, prompt-non-prompt and non-prompt di-J/psi
production and estimating also the DPS contribution. Single parton
scattering cross-sections are compared to cutting-edge theoretical
calculations in the colour singlet and colour octet formalisms.
