Description
We carry out a study of the light scalar meson a_0(980) employing
interpolating field operators of quark-antiquark, diquark-antidiquark,
mesonic molecules and two-particle meson operators. Both connected and
disconnected quark loops are investigated. We present preliminary results
for two ensembles of 2+1 clover fermion gauge configurations generated
by the PACS-CS collaboration with pion masses ~300 MeV and ~150 MeV.
