Abstract

We study SO(32) heterotic string theory on a torus with magnetic fluxes. Non-vanishing fluxes can lead to non-universal gauge kinetic functions for SU(3) × SU(2) × U(1)Y , which is an important feature of SO(32) heterotic string theory in contrast to the E₈ × E₈ theory. It is found that the experimental values of gauge couplings are realized with O(1) values of moduli fields based on realistic models with the SU(3) × SU(2) × U(1)Y gauge symmetry and three chiral generations of quarks and leptons without chiral exotics.
