Description
We investigate if the newly discovered mesons in the charm region, such as
D_s(2317), X(3872), Z^+(4430), are tetraquark mesoniums. With quarks and
antiquarks in periodic and antiperiodic boundary conditions respectively in
the spatial directions, we try to find out if the ground states from the
tetraquark interpolation fields are one meson or two meson states. We use
valence overlap fermions on 2+1 flavor domain wall fermion configurations.
$Z_4$ grid sources are adopted to increase statistics.
