چکیده
We study the charmonium spectrum including higher spin and exotic states. We use the Sheikholeslami-Wilson (clover) action for N f = 2 sea quarks as well as for the charm valence quark. In order to access excited states we apply a variational method with a basis of highly optimized operators.

We present results for charmonium correlators and spectral functions in 2-flavour QCD on anisotropic lattices. Our results indicate that the S-waves (J/ψ and η c) survive up to temperatures close to 2T c , while the P-waves (χ c0 and χ c1) melt away below 1.2T c. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

It was recently pointed out that simple scaling properties of Polyakov correlation functions of gauge systems in the confining phase suggest that the ratios of k-string tensions in the low temperature region is constant up to terms of order T 3. Here we argue that, at least in a three-dimensional Z4 gauge model, the above ratios are constant in the whole confining phase. This result is obtained...

We present results of a 2+1+1 flavor twisted mass lattice QCD computation of the spectrum of D mesons and Ds mesons and of charmonium. Particular focus is put on the positive parity D states (so-called D∗∗ mesons) with quantum numbers JP = 0+, 1+ and 2+. Besides computing their masses we are also separating and classifying the two JP = 1 states according to the angular momentum/spin of their li...

I review lattice QCD calculations that compute the masses of the flavour singlet pseudoscalar mesons. I describe the progress in computing the mass spectrum of light 0 ++ mesons using lattice QCD. I also compare the results for basic quantities such as f π and m ρ , from various different formalisms of lattice QCD. I discuss the physical value of r 0 .
