A Note on New Sources of Gaugino Masses
In IIB orientifold models, the singlet twisted moduli appear in the tree-level gauge kinetic function. They might be responsible for generating gaugino masses if they acquire non-vanishing F-terms. We discuss some aspects of this new possibility, such as the size of gaugino masses and their non-univ...
