Description
I will discuss recent progress in heavy quarkonium calculations from lattice QCD. Fully relativistic QCD on fine lattices -- with physical light and heavy quark masses, and realistic sea quark content -- allows precise determination of a number of charmonium and bottomonium properties such as meson masses and decay constants, which provide stringent tests of the strong interaction. Meson masses can subsequently be used to tune and make accurate determinations of quark masses from lattice QCD, while the decay constants can allow, in conjunction with annihilation rates from experiment, calculations of CKM matrix elements. I will discuss these and other important highlights from recent lattice QCD calculations including precise determinations of decay rates, comparing them to results from experiment.
