Mixing and mq dependence of axial vector mesons in the Coulomb gauge QCD model

We discuss pure qq¯ axial-vector mesons in the Tamm-Dancoff approximation of the Coulomb-gauge QCD model from North Carolina State University. While recent studies have put emphasis in configuration mixing with open meson-meson channels, we here concentrate on the simpler closed-channel problem and...

Description
Summary:We discuss pure qq¯ axial-vector mesons in the Tamm-Dancoff approximation of the Coulomb-gauge QCD model from North Carolina State University. While recent studies have put emphasis in configuration mixing with open meson-meson channels, we here concentrate on the simpler closed-channel problem and follow the 1+ mixing through a wide range of quark masses. We also examine their radial excitations and discuss with them the concept of insensitivity to chiral symmetry breaking.
