Hard hadron spectroscopy
arXiv:0710.0985
Abstract
I review lattice QCD calculations that compute the masses of the flavour singlet pseudoscalar mesons. I describe the progress in computing the mass spectrum of light 0++ mesons using lattice QCD. I also compare the results for basic quantities such as fpi and mrho, from various different formalisms of lattice QCD. I discuss the physical value of r0.
22 pages, 10 figures, plenary talk presented at the XXV International Symposium on Lattice Field Theory, 30 July - 4 August 2007, Regensburg, Germany. Changed the discussion of preliminary results for a0 and b1 masses from ETMC, because of an error in the analysis found while preparing arXiv:0906.4720
