Reheating processes after Starobinsky inflation in old-minimal
  supergravity
  We study reheating processes and its cosmological consequences in the
Starobinsky model embedded in the old-minimal supergravity. First, we consider
minimal coupling between the gravity and matter sectors in the higher curvature
theory, and transform it to the equivalent standard supergravity coupled to
additional matter superfields. We then discuss characteristic decay modes of
the inflaton and the reheating temperature $T_{\rm R}$. Considering a simple
model of supersymmetry breaking sector, we estimate gravitino abundance from
inflaton decay, and obtain limits on the masses of gravitino and supersymmetry
breaking field. We find $T_{\rm R}\simeq 1.0\times10^9$ GeV and the allowed
range of gravitino mass as $10^4$ GeV $\lesssim m_{3/2} \lesssim 10^5$ GeV,
assuming anomaly-induced decay into the gauge sector as the dominant decay
channel.
