  We study the formation of primordial black holes and the generation of
gravitational waves in a class of cosmological models that are direct
supersymmetric analogs of the observationally favored nonminimally coupled
Higgs inflation model. It is known that this type of model naturally includes
multiple scalar fields which may be regarded as the inflaton. For the sake of
simplicity we focus on the case where the inflaton field space is two
dimensional. We analyze the multifield dynamics and find the region of
parameters that gives copious production of primordial black holes that may
comprise a significant part of the present dark matter abundance. We also
compute the spectrum of the gravitational waves and discuss their detectability
by means of future ground-based and space-borne gravitational wave
observatories.
