Chiral Behaviour of the Rho Meson in Lattice QCD
In order to guide the extrapolation of the mass of the rho meson calculated in lattice QCD with dynamical fermions, we study the contributions to its self-energy which vary most rapidly as the quark mass approaches zero; from the processes ρ → ωπ and ρ → ππ. It turns out that in analysing the most recent data from CP-PACS it is crucial to estimate the self-energy from ρ → ππ using the same grid...

متن کاملExtrapolations of Lattice Meson Form Factors
Abstract We use chiral perturbation theory to study the extrapolations necessary to make physical predictions from lattice QCD data for the electromagnetic form factors of pseudoscalar mesons. We focus on the quark mass, momentum, lattice spacing, and volume dependence and apply our results to simulations employing mixed actions of Ginsparg-Wilson valence quarks and staggered sea quarks. To det...

متن کاملMeson-Meson and Meson-Baryon Interactions in Lattice QCD
We study the meson-meson and meson-baryon interactions in lattice QCD. The simulation is performed on 203 × 24 lattice at β = 5.7 using Wilson gauge action and Wilson fermion at the quenched level. By adopting one static quark for each hadron as “heavy-light meson" and “heavy-light-light baryon", we define the distance r of two hadrons and extract the inter-hadron potential from the energy diff...
