Mass formulae and natural hierarchy in string effective supergravities
We study some conditions for the hierarchy m_{3/2} << M_P to occur naturally in a generic effective supergravity theory. Absence of fine-tuning and perturbative calculability require that the effective potential has a sliding gravitino mass and vanishing cosmological constant, up to {\cal O}(m...
