N=1 No-scale Supergravity from Iib Orientifolds

  title={N=1 No-scale Supergravity from Iib Orientifolds},
  author={Massimo Porrati},
We describe the low-energy effective theory of N=1 spontaneously broken supegravity obtained by flux-induced breaking in the presence of n D3 branes. This theory can be obtained by integrating out three massive gravitino multiplets in the hierarchical breaking N = 4 → 3 → 2 → 1 of a N=4 orientifold. This integration also eliminates the IIB complex dilaton. The resulting theory is a no-scale supergravity model, whose moduli are the three chiral multiplets that correspond to the three radii of T2… CONTINUE READING
