Abstract

We discuss modifications of the gyromagnetic moment of electrons and muons due to a minimal length scale combined with a modified fundamental scale $M_{f}$ . First-order deviations from the theoretical standard model value for $g - 2$ due to these String Theory-motivated effects are derived. A constraint of $M_{f} > 577 G e V$ for the new fundamental scale is given.
