摘要：

Described is the new phenomenon of scalar S*-δ0 meson mixing which is shown to be considerable and to be determined by the strong interaction coupling constants of the S* and δ mesons with the KK channel and to be of the order of [(mK - mK)/mK] 1 2, and not of (mK - mK)/mK as would be expected from simple considerations. The reactions are discussed in which one can study this phenomenon. © 1979.
