摘要：I review lattice QCD calculations that compute the masses of the avour 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 fp and mr , from various different
formalisms of lattice QCD. I discuss the physical value of r0.
