dc.description.abstractWe present for smooth nonoscillating backgrounds an analytic formula which calculates the energy density of massive and massless particles created via gravitational particle production, thus giving the corresponding reheating temperature. It can be applied to models of quintessential inflation such as a -attractors, and shows that for masses larger than the Hubble rate at the end of inflation, namely H END , the reheating temperature is exponentially suppressed. On the contrary, for masses of the order of H END one obtains a maximum reheating temperature of the order of 10 7 ¿ ¿ GeV . Finally, to overcome the constraints coming from the overproduction of gravitational waves in quintessential inflation, we have shown that the viable masses which ensure the big bang nucleosynthesis success are in the range between 2 × 10 10 ¿ ¿ GeV and 4 × 10 13 ¿ ¿ GeV , leading to a maximum reheating temperature of the order 10 5 – 10 7 ¿ ¿ GeV
