英文摘要A complete analysis is given of the implications of the empirical indications for a positive strangeness magnetic moment mu(s) of the proton on the possible configurations of the uuds (s) over bar component of the proton. A positive value for mu(s) is obtained in the s (s) over bar configuration where the uuds subsystem is in an orbitally excited state with [4](FS)[22](F)[22](S) flavor-spin symmetry, which is likely to have the lowest energy. The configurations in which the (s) over bar is orbitally excited, which include the conventional K(+)Lambda(0) configuration, with the exception of that in which the uuds component has spin 2, yield negative values for mu(s). The hidden strangeness analogues of recently proposed quark cluster models for the theta(+) pentaquark give differing signs for mu(s).
