Gauge coupling unification in<i>SO</i>(32) heterotic string theory with magnetic fluxes
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 |$SU(3) \times SU(2) \times U(1)_Y$|, which is an important feature of |$SO(32)$| heterotic string theory in contrast to the |$E_8\times E_8$| theory. It is found that the experimental …
