论文摘要
我们研究了由超级启发的$ \ arctan $电位驱动的潮汐通货膨胀的背景下的早期宇宙演变。我们进行了缓慢的卷和半分析的再加热分析，并获得了与Planck 2018数据一致的通货膨胀参数的限制。我们还采用了马尔可夫链蒙特卡洛分析来执行宇宙学参数的参数估计，从而与当前可用的宇宙微波背景和Baryon声学振荡数据相吻合。这项工作确立了$ \ arctan $模型的一般理论预测，统计分析的结果证实了其观察性生存能力。
We investigate the early universe evolution in the context of brane inflation driven by a supergravity-inspired $\arctan$ potential. We performed a slow-roll and a semi-analytical reheating analyses and obtained constraints on the inflationary parameters in agreement with Planck 2018 data. We also employed a Markov Chain Monte Carlo analysis to perform a parameter estimation of the cosmological parameters, obtaining results in good agreement with the currently available cosmic microwave background and baryon acoustic oscillation data. This work establishes the general theoretical predictions of the $\arctan$ model, with the results of the statistical analysis corroborating its observational viability.
