Excited charmonium physics from lattice QCD

Jozef J. Dudek, Marvin L. Marshak
2009
Properties of excited mesons are studied using a lattice QCD simulation of a system comparable to charmonium. We extract a spectrum of states, including those with manifestly exotic quantum numbers. Radiative transition form-factors are also computed, in particular the transition from exotic η c1 to J/ψγ which is found to be large on the usual scale of magnetic dipole transitions.
