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 distributions of the collected double $J/\psi$ events are analysed, and

Lepton pair production in muon scattering by nucleus

Autor: Berezhnoy, A. V., Koshkarev, S. N., Luchinsky, A. V., Nikolaenko, V. I.

Coherent production of lepton pair in muon scattering by nucleus is considered. With the help of different approaches (equivalent photon approximation, direct numerical and analytical calculations) we obtain total cross section of this reaction and d
