Phys. Rev. D 72, 036010 (2005) [10 pages]Experimental tests of charge symmetry violation in parton distributionsReceived 4 July 2005; published 29 August 2005 Recently, a global phenomenological fit to high energy data has included charge symmetry breaking terms, leading to limits on the allowed magnitude of such effects. We discuss two possible experiments that could search for isospin violation in valence parton distributions. We show that, given the magnitude of charge symmetry violation consistent with existing global data, such experiments might expect to see effects at a level of several percent. Alternatively, such experiments could significantly decrease the upper limits on isospin violation in parton distributions. © 2005 The American Physical Society URL:
