Abstract: (Springer)
Cross sections for JI-meson pair production in proton-proton interaction at the c.m. collision energy of TeV were theoretically predicted under conditions of various kinematical cuts. The possible contribution to this process from the decays of 4c tetraquarks, new hypothetic particles consisting of two valence c quarks and two valence antiquarks, was studied. It is shown that at least one such state (tensor 4c tetraquark) can in principle be observed experimentally under conditions of the LNCb experiment.- J/psi(3100): pair production
