Light scalar mesons in 2+1 flavor full QCD ^∗

Research output: Contribution to journal › Conference article › peer-review

Abstract

We study the a₀ and K₀ ^∗ light scalar mesons in 2+1 flavor full QCD. Particular attention is paid to fitting excited states, with an eye toward determining whether scattering states are revealed. An ultimate goal will be to see how dynamical quarks affect the picture outlined with an earlier quenched study using overlap fermions, namely, that it is the a₀(1450), not the a₀(980), which is the lowest qq isovector scalar state.
