Paired charmonium and bottomonium production in rare exclusive decays of Z boson
F. A. Martynenko, A. P. Martynenko, A. A. Skakun
Abstract
The processes of paired charmonium and bottomonium production in Z-boson decays are investigated within the relativistic quark model. Various decay mechanisms are examined, and relativistic decay amplitudes are constructed, taking into account the relative momenta of heavy quarks. Decay widths are calculated for various mechanisms in the nonrelativistic approximation and taking into account relativistic corrections.
