The most precise measurement yet of strange quarks in the proton, performed at the Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab) by the second phase of the Hall A Proton Parity Experiment (HAPPEx II), shows that the strange quark contribution to the proton's overall charge distribution and magnetic moment is small, indeed: it's so small, at less than 1 percent of the proton's charge distribution and no more than 4 percent of its magnetic moment, that it may be zero.
