Predicted charged charmonium-like structures in the hidden-charm dipion decay of higher charmonia
charged charmonium-like dipion decay
2011/7/21
In this work, we predict two charged charmonium-like structures close to the $D^\ast\bar{D}$ and $D^\ast\bar{D}^\ast$ thresholds, where the Initial Single Pion Emission mechanism is introduced in the ...
Novel charmonium-like structures in the $J/\psi\phi$ and $J/\psi\omega$ invariant mass spectra
Novel charmonium-like structures
2011/1/7
Stimulated by the new evidence of Y(4274) observed in the J/ invariant mass spectrum, we first propose the charmonium-like state Y(4274) as the S-wave Ds ¯D s0(2317) + h.c. molecular state with...
Production of charmonium(like) states in e+e－ interactions
charmonium new states e+e－ annihilation initial state radiation
2009/8/14
We present a search for new charmonium like states in e+e－ annihilation using the initial-state radiation and the process e+e－J/ψD(*)D(*). The analyses are based on a huge data sample recorded near th...

initial state radiation cross section charmonium charmed mesons
2009/8/14
The cross sections for e+e－→π+π－J/ψ, π+π－ψ(2S), K+K－J/ψ, DD, D0D－+π++c.c., D*D+c.c., and D*D* are measured using data sample collected on or near the Υ(4S) resonance with the Belle detector at KEKB. A...
Some topics on charmonium decays at BESⅢ experiment
BESⅢ charmonium decays spin-singlet charmonium spin-triplet charmonium hyperon decay parameter
2009/8/14
The construction of BESⅢ detector has been finished and the data taking is under plan. Some physics topics on charmonium decays at BESⅢ experiment are discussed in this paper. The measurement of prope...
A Semi-Classical Picture of the Charmonium-Hadron Interaction
A Semi-Classical Picture the Charmonium-Hadron Interaction an external color field
2010/10/19
In this work, we present calculations for the charmonium-hadron cross section. The hadron is represented by an external color field and the charmonium is represented by a small color dipole. Using hig...
