摘要：

We have extended and improved our previous studies of the qqq» q» system, paying special attention to the KK» channels. The new results clarify and reinforce the KK» molecule interpretation of the S* and Effective meson-meson potentials extracted from the qqq q system and couplings to qq scalar mesons lead to coupled-channel amplitudes which closely resemble those observed in both the S* and channels. We also show that the KK molecules have properties consisent with experimental results on the production of the S* and of low-mass KK» pairs. © 1990 The American Physical Society.
