Revisiting the production of $$J/\psi $$ J / ψ pairs at the LHC
Abstract We consider the prompt double $$J/\psi $$ J / ψ production in pp collisions at the LHC in the framework of $$k_T$$ k T -factorization QCD approach. Using the fragmentation mechanism, we evaluate the color octet contributions to the production cross sections taking into account the combinato...
