Exotic and excited-state radiative transitions in charmonium from lattice QCD

Christopher Thomas
JLab

I will discuss recent calculations of meson radiative transition form factors 
in lattice QCD.  Results in the charmonium region, involving excited charmonium 
states, states of high spin and exotics, will be presented and I will highlight 
interesting results involving an exotic 1-+ and a vector-hybrid candidate.  I 
concentrate on the phenomenology of the results, comparing with experimental 
data and with models.  To conclude I give comments on future prospects, 
including application to light mesons.
