Chiral Loop Effects in the Quenched Scalar Isovector Propagator

High Energy Physics - Lattice 2014-11-17 v1

Abstract

The scalar isovector meson propagator is studied in quenched QCD. For the lightest quark masses used, this propagator is dominated by a quenched chiral loop effect associated with the η\eta'-π\pi two-meson intermediate state. Both the time dependence and the pion mass dependence of the effect are well-described by quenched chiral perturbation theory.
