Bubble contributions to scalar correlators with mixed actions

  • Within mixed-action chiral perturbation theory (MAχPT), Sasa's derivation of the bubble contribution to scalar a0 meson is extended to those of scalar k and σ mesons. We revealed that the k bubble has two double poles and the σ bubble contains a quadratic-in-t2 growth factor stemming from the multiplication of two double poles for a general mass tuning of valence quarks and sea quarks. The corresponding preliminary analytical expressions in MAχPT with 2+1 chiral valence quarks and 2+1 staggered sea quarks will be helpful for lattice studies of scalar mesons.

Bubble contributions to scalar correlators with mixed actions

    Corresponding author: FU Zi-Wen,

Abstract: Within mixed-action chiral perturbation theory (MAχPT), Sasa's derivation of the bubble contribution to scalar a0 meson is extended to those of scalar k and σ mesons. We revealed that the k bubble has two double poles and the σ bubble contains a quadratic-in-t2 growth factor stemming from the multiplication of two double poles for a general mass tuning of valence quarks and sea quarks. The corresponding preliminary analytical expressions in MAχPT with 2+1 chiral valence quarks and 2+1 staggered sea quarks will be helpful for lattice studies of scalar mesons.
