Abstract

Effective dimension-5 operators which modify the gauge kinetic term in Grand Unified Theories may arise as a consequence of quantum gravity or string compactification. We exhaustively calculate the modification of the gauge unification condition due to such operators for all viable rank-preserving symmetry breakings of SO(10) and E(6) grand unified models.
