Electro-weak production of pseudovector C-even heavy quarkonia in electron-positron collisions on Belle II and BES III
It is shown that the molecular model for the X{3872) state contradicts the new experimental data as well as the old ones. It is suggested to study the χ_{c1} and χ_{b1} states in the e+e-\toχ_{c1}/χ_{b1} reactions.
