标题： The Preheating Stage on The Starobinsky Inflation after ACT

摘要： 在本文中，我们重新研究了Starobinsky膨胀及其在ACT结果后的再加热特性。 为了使Starobinsky模型符合ACT的$68\%$CL，e折叠数增加到$>70$，而再加热温度降至$10^4$GeV。 预加热阶段和再加热温度需要大幅调整以适应较低的温度。 我们得出结论，Starobinsky膨胀的预加热阶段应在快子和非快子预加热之间混合，以同时有利于分析估计、PBH丰度和低再加热温度。 为此，需要一个变化的动量来获得有利的结果。 显示英文摘要

摘要： In this paper, we reinvestigate the Starobinsky inflation and its reheating features after the ACT results. To make the Starobinsky model satisfy ACT with $68\%$ CL, the number of e-folds increases to $>70$ while the reheating temperature drops to $10^4$ GeV. The preheating stages and the reheating temperature need to be adjusted drastically in favor of the lower temperature. We obtain that the preheating stage of Starobinsky inflation should be mixed between tachyonic and non-tachyonic preheating to favor the analytical estimation, PBH abundance, and the low reheating temperature at once. For that purpose, a varied momentum is necessary to obtain the favored results.
