Abstract :
We discuss the mediation of supersymmetry breaking from closed to open strings, extending and improving previous analysis of the authors in [I. Antoniadis, T.R. Taylor, Nucl. Phys. B 695 (2004) 103, ]. In the general case, we find the absence of anomaly mediation around any perturbative string vacuum. When supersymmetry is broken by Scherk–Schwarz boundary conditions along a compactification interval perpendicular to a stack of D-branes, the gaugino acquires a mass at two loops that behaves as image in string units, where image is the gravitino mass and g is the gauge coupling.
