It is shown how the partonic content of various structure functions gets redefined when the assumption of charge symmetry is relaxed. Various theoretical and phenomenological models for charge-symmetry violation in parton distribution functions are reviewed. After summarizing the current experimental upper limits on charge-symmetry violation in parton distributions, a series of new experiments are proposed, which might reveal partonic charge-symmetry violation or alternatively might lower the current upper limits on parton charge-symmetry violation.en© 2010 The American Physical SocietyCharge symmetry at the partonic levelJournal article002010283310.1103/RevModPhys.82.20090002798062000012-s2.0-7795615665532350Thomas, A.
