Description
In electron-positron annihilation, the process of e+e- -> chi_c1 can occur via the
production of two virtual photons or through neutral current, therefore being suppressed with
respect to the normal annihilation process via one virtual photon. Using a dedicated scan sample
around the chi_c1 mass, the direct production of chi_c1 has been established for the first time
in experiments. This provides a new approach for the study of the internal nature of hadrons.
