چکیده

We present a progress report on our study of the charmonium spectrum in full QCD on anisotropic lattices generated by the Hadron Spectrum Collaboration. We adopt a large basis of interpolating operators to extract the excited charmonium states using the variational method. A detailed spectrum of excited charmonium mesons in many JPC channels is obtained. Hybrid states with exotic and non-exotic quantum numbers are determined and preliminary results from a study of disconnected contributions to the ηc are presented.

Hybrid charmonium from lattice QCD∗

We review our recent results on the J PC = 0 −− exotic hybrid charmonium mass and J PC = 0 −+ , 1 −− and 1 ++ nonexotic hybrid charmonium spectrum from anisotropic improved lattice QCD and discuss the relevance to the recent discovery of the Y (4260) state and future experimental search for other states.

Exotic and higher spin mesons in charmonium

Exotic and higher spin (> 1) mesons are still not throughly investigated in lattice QCD. Using a set of derivative based operators we report our exploratory study of these mesons in charmonium region. We use a 123 × 48 anisotropic (ξ = 3) clover lattice with inverse temporal lattice spacing a−1 = 6.05 GeV. Techniques developed in this exploratory study will be utilized in our future comprehensi...

Charmonium properties at finite temperature on quenched anisotropic lattices

We study charmonium properties below and above Tc up to 1.8Tc, on quenched anisotropic lattices. Information of the spectral functions is extracted using the maximum entropy method and the constrained curve fitting. We also calculate the color singlet and averaged free energies and evaluate the charmonium spectrum with the potential model analysis. The relation between the lattice result of the...

Charmonium spectrum from quenched QCD on anisotropic lattices

We present our final results of the charmonium spectrum in quenched QCD on anisotropic lattices. Simulations are made with the plaquette gauge action and a tadpole improved clover quark action employing ξ = as/at = 3. We calculate the spectrum of Sand P-states and their excitation, and study the scaling behavior of mass splittings. Comparison is made with the experiment and previous lattice res...

Lattice QCD review of charmonium and open-charm spectroscopy

Lattice QCD results on the spectroscopy of charmonium(like) states and open charm mesons are reviewed. Near-threshold states X(3872) and D s0(2317) were treated rigorously for the first time and the searches for Z c (3900), X(4140) and ccud were carried out. The first simulations of the resonances with charm quarks have been performed, including the determination of their strong decay widths. S...
