FROM THE CURRENT LITERATURE: On the nature of the a0(980) and f0(980) scalar mesons
Abstract
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.
