Quark model analysis of strangeness form factors of the proton

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.
