Abstract
Hybrid inflation is a natural scenario in the absence of super- symmetry. In the context of supergravity, however, it has to face the naturalness problems of the initial conditions and of the adequate suppression of the inflaton mass. Both can be successfully addressed in a class of models involving Kähler potentials associated with products of SU(1, 1)/U(1) Kähler manifolds and “decoupled” fields acquiring large vacuum expectation values through D-terms.
