| Abstract: | We extend the method of infrared regularization to spin-1 fields. As applications, we discuss the chiral extrapolation of the rho meson mass from lattice QCD data and the pion-rho sigma term.Received: 18 November 2004, Published online: 4 February 2005PACS: 12.39.Fe, 12.38.GcWork supported in part by Deutsche Forschungsgemeinschaft through grants provided for the SFB/TR 16  Subnuclear Structure of Matter . |
