Abstract
We compare flavour singlet and non-singlet vector mesons from first principles using lattice QCD. With Nf=2 flavours of light quark, this addresses the Ï-Ï mass difference. Using maximally twisted-mass lattice QCD, we are able for the first time to determine this mass difference precisely and we compare with experiment. We also discuss Ï-Ï mixing effects arising within QCD through the u-d quark mass difference.
