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 \( \bar s \) configuration has the flavor spin symmetry [4] FS [22] F [22] S , mixed orbital symmetry [31] X and that the \( \bar s \) is in the ground state. This uuds \( \bar s \) 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 \( \bar s \) components are significant.
