Quenched charmonium spectrum on anisotropic lattices

چکیده
We present the results of quenched charmonium spectrum for Sand P-states, obtained by a relativistic heavy quark method on anisotropic lattices. Simulations are carried out using the standard plaquette gauge action and a meanfield-improved clover quark action at a−1 t = 3–6 GeV with the renormalized anisotropy fixed to ξ ≡ as/at = 3. We study the scaling of our fine and hyperfine mass splittings, and compare with previous results.

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...
متن کاملCharmonium 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...
متن کاملExcited charmonium spectrum from anisotropic lattices
We present our final results for the excited charmonium spectrum from a quenched calculation using a fully relativistic anisotropic lattice QCD action. A detailed excited charmonium spectrum is obtained, including both the exotic hybrids (with J = 1−+, 0+−, 2+−) and orbitally excited mesons (with orbital angular momentum up to 3). Using three different lattice spacings (0.197, 0.131, and 0.092 ...
متن کاملHeavy Quarks on Anisotropic Lattices: The Charmonium Spectrum
We present results for the mass spectrum of cc̄ mesons simulated on anisotropic lattices where the temporal spacing at is only half of the spatial spacing as. The lattice QCD action is the Wilson gauge action plus the clover-improved Wilson fermion action. The two clover coefficients on an anisotropic lattice are estimated using mean links in Landau gauge. The bare velocity of light νt has been ...
متن کاملContribution of charm anihilation to the hyperfine splitting in charmonium in the quenched case
In calculations of the hyperfine splitting in charmonium, the contributions of the disconnected diagrams is considered small and is typically ignored. We aim to estimate nonperturbatively the size of the resulting error, which could potentially affect the high precision calculations of the charmonium spectrum. Following our work on the effects of the disconnected diagrams in unquenched QCD pres...
