Wicklund, A B

We review recent analyses of J/sup PC/ = O/sup + +/ mesons in the ..pi pi.., anti KK and ..pi..K channels. These analyses point to the existence of Q anti Q nonet in the mass range 1300 to 1600 MeV with fairly well established members, which we donate as epsilon(1425) and kappa(1450). Other S-wave effects, which we label by epsilon(800) and kappa(800), occur as backgrounds in ..pi pi.. and K..pi.. scattering. The S*(980) effect is shown to be inconsistent with a normal width hadron, and is probably a bound state of the anti KK system.
