论文摘要
我们为平滑的非振荡背景提供了一种分析公式，该公式计算通过重力颗粒产生产生的质量和无质量颗粒的能量密度，从而给出了相应的加热温度。它可以应用于典型通货膨胀的模型，例如$α$ - 吸引者，并表明，对于通货膨胀结束时的质量大于哈勃速率，即$ h_ {end} $，重新加热温度被指数抑制。相反，对于$ h_ {end} $的订单的质量，一个人获得了$ 10^7 $ gev的最高加热温度。 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 {$2\times 10^{10}$ GeV and $ 4\times 10^{13}$ GeV}, leading to a maximum reheating temperature of the order {$10^5-10^7$ GEV}。
We present for smooth non-oscillating 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 $α$-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 {$2\times 10^{10}$ GeV and $ 4\times 10^{13}$ GeV}, leading to a maximum reheating temperature of the order {$10^5-10^7$ GeV}.
