摘要
En 中文
We argue that relatively compact charmonium states, J/Psi, Psi(2S), chi(c), can very likely be bound inside light hadronic matter, in particular inside higher resonances made from light quarks and/or gluons. The charmonium state in such binding essentially retains its properties, so that the bound system decays into light mesons and the particular charmonium resonance. Thus such bound states of a new type, which we call hadro-charmonium, may explain the properties of some of the recently observed resonant peaks, in particular of Y(4.26), Y(4.32-4.36), Y(4.66), and Z(4.43). We discuss further possible implications of the suggested picture for the observed states and existence of other states of hadro-charmonium and hadro-bottomonium. (C) 2008 Elsevier B.V.
