On the nature of the a0(980) and f0(980) scalar mesons


S.L. Sobolev Institute for Mathematics, Siberian Branch of the Russian Academy of Sciences, prosp. akad. Koptyuga 4, Novosibirsk, 630090, Russian Federation

The unusual properties of the a0(980) and f0(980) scalar mesons are discussed in terms of the four-quark, two-quark, and molecular models. Arguments in favor of the four-quark model are given. Further studies needed to resolve the problem are discussed.
