Mass predictions are presented for both conventional q ¯ q meson and q ¯ qq ¯ q tetra-quark states. Mixing matrix elements between these states were also computed and diagonalized to provide a reasonable description of the scalar spectrum below 2 GeV. 978-0-7354-0554-7 10.1063/1.2973493 https://hdl.handle.net/20.500.14352/53321 http://dx.doi.org/10.1063/1.2973493 http://arxiv.org/abs/0804.3837 http://scitation.aip.org Coulomb gauge approach to scalar hadrons
