摘要
We discuss recent progress in extracting the excited meson spectrum and radiative transition form factors from lattice QCD We mention results in the charmonium sector, including the first lattice QCD calculation of radiative transition rates involving excited charmonium states; highlighting results for high spin and exotic states We present recent results on a highly excited isovector meson spectrum from dynamical anisotropic lattices Using carefully constructed operators we show how the continuum spin of extracted states can be reliably identified and confidently extract excited states, states with exotic quantum numbers and states of high spin This spectrum includes the first spin-four state extracted from lattice QCD We conclude with some comments on future prospects
