      abstract     = {We address the question whether the lightest scalar mesons
                      sigma and kappa are tetraquarks. We present a search for
                      possible light tetraquark states with $J^PC=0^++$ and I=0,
                      1/2, 3/2, 2 in the dynamical and the quenched lattice
                      simulations using tetraquark interpolators. In all the
                      channels, we unavoidably find lowest scattering states
                      pi(k)pi(-k) or K(k)pi(-k) with back-to-back momentum
                      k=0,2*pi/L,.. . However, we find an additional light state
                      in the I=0 and I=1/2 channels, which may be related to the
                      observed resonances sigma and kappa with a strong tetraquark
                      component. In the exotic repulsive channels I=2 and I=3/2,
                      where no resonance is observed, we find no light state in
                      addition to the scattering states.},
