A new slant on hadron structure

Rather than regarding the restriction of current lattice QCD simulations to quark masses that are 5-10 times larger than those observed as a problem, we note that this presents a wonderful opportunity to deepen our understand ing of QCD. Just as it has been possible to learn a great deal about QCD by treating N. as a variable, so the study of hadron properties as a function of quark mass is leading us to a deeper appreciation of hadron structure. As examples we cite progress in using the chiral properties of QCD to conne ct hadron masses, magnetic moments, charge radii and structure functions ca lculated at large quark masses within lattice QCD with the values observed physically.
