The role of initial gluon emission in double $J/\psi$ production at central rapidities

S. P. Baranov, A. V. Lipatov, A. A. Prokhorov

We consider the process of double $J/\psi$ production in $pp$ collisions at the LHC in the framework of $k_T$-factorization approach. We focus on the gluon fragmentation mechanism whi…
