Theoretical Analysis of Static Hyperon Data for HYPERON99

We consider all hyperon data relevant to spin and flavor structure of hyperons. In addition to masses and magnetic moments considered as static properties in Hyperon99 we include also relevant data from hyperon decays and spin structure determined from deep inelastic scattering. Any theoretical model for the hyperons with parameters to be determined from experiment should use input from all these data. Of particular interest are new data from $\Xi^o$ decay and the polarixation of $\Lambda's$ produced in Z^o decays and deep inelastic scattering.
