Manifestation of intermediate meson loop effects in charmonium decays

  • We report the progress on understanding some of those existing puzzles in charmonium decays. We show that the intermediate meson loops (IML) as a long-distance transition mechanism will provide novel insights into these issues. In particular, we show that the
    IML mechanism would be essentially important for understanding the ψ(3770) non- DD decays. We also comment that such a mechanism is correlated with the Okubo-Zweig-Iizuka (OZI) rule evasions in charmonium hadronic decays.

Manifestation of intermediate meson loop effects in charmonium decays

    Corresponding author: ZHAO Qiang,

Abstract: 

We report the progress on understanding some of those existing puzzles in charmonium decays. We show that the intermediate meson loops (IML) as a long-distance transition mechanism will provide novel insights into these issues. In particular, we show that the
IML mechanism would be essentially important for understanding the ψ(3770) non- DD decays. We also comment that such a mechanism is correlated with the Okubo-Zweig-Iizuka (OZI) rule evasions in charmonium hadronic decays.
