Double parton scattering as a source of quarkonia pairs in LHCb

Abstract

Recent results on production of $J/\psi$ pairs in LHCb initiated discussion on double parton scattering (DPS) contribution to this process, which is not yet elaborated well. In this short report $J/\psi {\chi }_c$ and $J/\psi {\rm Y}$ modes are proposed for DPS studies. Estimations for ${\rm Y}{\rm Y}$ and $J/\psi {\rm Y}$ production in LHCb are presented.
