“…On the experimental side, such a two-photon transition process has already been studied in the 1970s and 1980s [29,30]. In recent years, more precise measurements were carried out by the BESIII [31,32] and CLEO [33,34] Collaborations. However, they focused on the investigation of the cascade decay ψ(2S) → χ cJ + γ followed by χ cJ → J/ψ + γ and on the study of the properties of the χ cJ states.…”

The decay mode ψ(2S) → J/ψ + γγ is proposed in order to experimentally identify the effects of the coupling of charmonium states to the continuum DD states. To have a better understanding of such two-photon decay process, in this work we restrict ourselves to investigate the contribution of the discrete part, in which the photons are mainly produced via the intermediate states χ cJ (nP ).Besides calculating the resonance contributions of χ cJ (1P ) (J = 0, 1, 2), we also take into account the contributions of the higher excited states χ cJ (2P ) and the interference effect among the 1P and 2P states. We find that the contribution of the 2P states and the interference terms to the total decay width is very tiny. However, for specific regions of the Dalitz plot, off the resonance peaks, we find that these contributions are sizable and should also be accounted for. We also provide the photon spectrum and study the polarization of J/ψ.

The cornerstone of the Chinese experimental particle physics program consists of a series of experiments performed in the tau-charm energy region. China began building e + e − colliders at the Institute for High Energy Physics in Beijing more than three decades ago. Beijing Electron Spectrometer, BES, is the common root name for the particle physics detectors operated at these machines. The development of the BES program is summarized and highlights of the physics results across several topical areas are presented.
