Reheating constraints in quintessential inflation
We study the consequences of reheating in quintessential inflation. From simple inflationary quintessential models introduced by de Haro, Amorós, and Pan in [Phys. Rev. D 93, 084018 (2016)] and [Phys. Rev. D 94, 064060 (2016)], we show that when the reheating is due to the production of heavy massiv...

| Resumo: | We study the consequences of reheating in quintessential inflation. From simple inflationary quintessential models introduced by de Haro, Amorós, and Pan in [Phys. Rev. D 93, 084018 (2016)] and [Phys. Rev. D 94, 064060 (2016)], we show that when the reheating is due to the production of heavy massive particles conformally coupled with gravity, a viable model which matches with the current observational data is only possible for reheating temperatures that range between 1 GeV and 10^4¿GeV. On the other hand, when the Universe reheats via the production of massless particles, viability of the model is only possible when those particles are nearly conformally coupled with gravity, leading to a reheating temperature between 1 MeV and 10^4 GeV. |
