abstract

The cross section values of $J/\psi\ \eta_c$ and $J/\psi\ J/\psi$ production in $e^+e^-$ annihilation are estimated within one-loop approximation near $Z$ pole, as well as at higher energies. Both intermediate bosons, $\gamma$ and $Z$, are taken into account. It is shown that at $Z$ mass the NLO contribution increases the cross-section values by 3.5 times.

Double heavy quarkonia production with color-octet channels at Z factory and at the CEPC/FCC-ee
hep-ph 2025-01 conditional novelty 5.0 of 10

Color-octet channels are predicted to dominate many double heavy quarkonium production processes at future Z factories, with relativistic corrections suppressing charmonium rates by roughly a factor of two.
