ar X iv : h ep - p h / 05 07 17 7 v 1 1 4 Ju l 2 00 5 Possible Molecular Structure of the Newly Observed Y ( 4260 ) March 5 , 2008
We suggest that the newly observed resonance Y (4260) is a χ c − ρ 0 molecule. In this picture, we can easily interpret why Y (4260) → π + π − J/ψ has a larger rate than Y (4260) → D ¯ D and we also predict another two possible partner states which may be observed in the future experiments. A direct consequence of this structure is that for this molecular structure Y (4260) → π + π − J/ψ mode i...

The recently observed Y(4260) lies far above the decay threshold with a width less than 100 MeV. We argue that it’s very difficult to accommodate Y(4260) as a conventional cc̄ radial excitation or a D-wave state. It can’t be a hadronic molecule. Its production mechanism and special decay pattern do not favor the glueball interpretation. If Y(4260) is a scalar tetraquark, it must be produced by t...

متن کاملA Uniform Description of the States Recently Observed at B-factories
The recently observed states Y(4260), Y(4361), Y(4664) and Z(4430) intriguing a great interests in both theory and experiment about the spectroscopy in the scope of conventional charmonium energy scale. The Y(4260) which was observed earlier has been interpreted as hybrid, molecular state, and baryonium, etc. In this work we show for the first time that these new structures, which are hard to b...
متن کاملOne Explanation for the Exotic State Y(4260)
We find in this work that the newly discovered state Y(4260), which with the mass lying in the normal charmonium spectrum energy scale, by the BaBar Collaboration could be embedded in a molecular state picture. However, in our model this molecular-like state is not constructed by the two-quark mesons, but rather by baryons, that is the baryonium. In this picture, the observed nature of this sta...
متن کاملCLEO-c Hot Topics
Selected recent results and future prospects for the CLEO-c experiment at CESR are reviewed. The topics covered include measurements of leptonic and semileptonic charm decays made with data collected at the ψ(3770) resonance and results from a scan of the center-of-mass energy range from 3970 to 4260 MeV addressing the details of open-charm production and properties of the Y (4260) state observ...
