Charmonium spectroscopy from an anisotropic lattice study

High Energy Physics - Lattice 2015-03-19 v1

Abstract

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 JPCJ^{PC} 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\eta_c are presented.
