Quark model analysis of strangeness form factors of the proton

The present empirical information on the proton strangeness form factors suggests that the uuds subsystem of the uuds anti s configuration has the flavor spin symmetry [4]FS[22]F[22]S, mixed orbital symmetry [31]X and that the anti s is in the ground state. This uuds anti s configuration yields the empirical signs for both the form factors GEs and GMs. Transition matrix elements between the uud and uuds anti s components are significant. (orig.)
