Double $J/\psi$ production in pion-nucleon scattering at COMPASS

G. D. Alexeev, M. G. Alexeev, A. Amoroso +191

We present the study of the production of double $J/\psi$ mesons using COMPASS data collected with a 190 GeV/$c$ ${\pi }^{-}$ beam scattering off NH${}_3$, Al and W targets. Kinematic distri…
