摘要:We study the a0 and K∗
0 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.
