The Proton's Strange Magnetism

The proton is made of three quarks--two up quarks and one down quark--but other types constantly flit into and out of existence. The 26 August PRL provides the first detailed picture of strange quarks in this mix and indicates that they make a significant contribution to the proton's properties. About 5% of the proton's magnetic moment comes from strange quarks, according to the results, although theoretical predictions have been ten times smaller. The discrepancy highlights the serious limitations in the current calculation techniques.
