Abstract We study the possibility that the light scalar mesons are q 2 q 2 states rather than q q . We perform a lattice QCD calculation of pseudoscalar meson scattering amplitudes, ignoring quark loops and quark annihilation, and find indications that for sufficiently heavy quarks there is a stable four-quark bound state with J PC =0 ++ and non-exotic flavor quantum numbers.
