  We propose a non-oscillatory no-scale supergravity model of inflation (NO-NO
inflation) in which the inflaton does not oscillate at the end of the
inflationary era. Instead, the Universe is then dominated by the inflaton
kinetic energy density (kination). During the transition from inflation to
kination, the Universe preheats instantly through a coupling to Higgs-like
fields. These rapidly annihilate and scatter into ultra-relativistic matter
particles, which subsequently dominate the energy density, and reheating occurs
at a temperature far above that of Big Bang Nucleosynthesis. After the
electroweak transition, the inflaton enters a tracking phase as in some models
of quintessential inflation. The model predictions for cosmic microwave
background observables are consistent with Planck 2018 data, and the density of
gravitational waves is below the upper bound from Big Bang Nucleosynthesis. We
also find that the density of supersymmetric cold dark matter produced by
gravitino decay is consistent with Planck 2018 data over the expected range of
supersymmetric particle masses.
