Abstract

The present empirical information on the proton strangeness form factors suggests that the uuds subsystem of the uuds¯ configuration has the flavor spin symmetry [4]_FS[22]_F[22]_S , mixed orbital symmetry [31]_X and that the ¯ is in the ground state. This uuds¯ configuration yields the empirical signs for both the form factors G _E ^s and G _M ^s . Transition matrix elements between the uud and uuds¯ components are significant.
