Charmonium resonances on the lattice


  • Dr. Stefano PIEMONTE

Primary authors


Many experiments have found evidence of charmonium-like states that do not fit into conventional models of quark-antiquark mesons. Non-perturbative insight provided by lattice simulations can help in understanding the properties of those states. The computation of single and multiparticle correlators is the main challenge of the numerical investigation of unstable states on the lattice. We extract the phase shift and the properties of the resonances from the finite volume energy levels. We present our preliminary results for the charmonium states near the threshold in the quantum channel 1-- and 0++. The target of our analysis are the resonances psi(3770) and X(3915).
