自大型强子对撞机（LHC）发现希格斯粒子以来，众多暴胀模型将其用作暴胀子。本研究首先证实希格斯暴胀在幺模引力框架下是一种可行的模型，随后探讨了与再加热相关的一种情形——再加热在连接暴胀时代与热大爆炸宇宙的过程中发挥着关键作用。此外，我们根据该再加热阶段的状态方程参数（$ω_{re}$），计算了温度、e折叠数等关键参数。目前再加热过程背后的物理机制仍极不明确，我们仅掌握范围非常有限的$ω_{re}$可接受取值。我们分析了该模型与Planck2018、BICEP/Keck2021、DESI2024及ACT阵列观测限制的相容性，发现该模型中$ω_{re}$被限制在$ -1 \leq ω_{re} \leq \frac{1}{6} $的范围内。
英文摘要
Since the discovery of the Higgs particle in the LHC, numerous inflationary models utilize it as the inflaton. In this study, after establishing that Higgs inflation can be a viable model in the context of unimodular gravity, we address a scenario related to reheating, which plays a crucial role in connecting the inflationary era to a hot Big Bang universe. Also, we calculate essential parameters such as the temperature and the e-folds number according to the equation of the state parameter ($ω_{re}$) in this regime of reheating. The physics behind the reheating process are extremely imprecise at present, and we have only a very limited range of acceptable values for $ω_{re}$. We analyze the compatibility with Planck2018, BICEP/Keck2021, DESI2024, and ACT array bounds and find that within this model, $ω_{re}$ is restricted to the range $ -1 \leq ω_{re} \leq \frac{1}{6} $.
