Neutral mesons and disconnected diagrams in Twisted Mass QCD

Presenter: Chris Michael — University of Liverpool

Chris Michael

We evaluate properties of neutral mesons in Nf=2 dynamical simulations of TMQCD. The pion is explored - establishing the size of the isospin splitting (an order a2 effect). We investigate the eta' (the Nf=2 flavour singlet). We show that disconnected diagrams can be evaluated very efficiently in TMQCD using variance reduction methods.
