论文摘要

我们考虑在五维时空中的通货膨胀,而充气领域仅限于牛世界。在这种情况下,我们研究了反气质的不同类型的潜力,讨论它们的观察后果并与数据进行比较。我们发现,某些类别的潜力与观察符合观察的吻合,并且充气场的价值可以是亚平晶。此外,我们在这种情况下研究了Swampland标准,并确定模型与猜想的一致性。这样做,我们可以确定同时满足观察数据和滚动标准的模型。通过研究加热阶段,可以应用更多限制,在该阶段中,加热温度的可接受范围在模型上施加了一些界限。作为最后一步,在显示TCC的约束的情况下,考虑了模型的跨普兰克审查猜想的结果,并且可以用来对Brane张力施加限制。

We consider inflation in a five -dimensional space time with the inflaton field confined to live on a brane world. In this scenario, we study different types of potentials for the inflaton, discuss their observational consequences, and compare with data. We find that some class of potentials are in good agreement with observation and that the value of the inflaton field can be sub-Planckian. Moreover, we investigate the swampland criteria in this scenario and determine the consistency of the model with the conjectures. Doing so, we could determine models that simultaneously satisfy both observational data and swampland criteria. More constraints are applied by studying the reheating phase where the acceptable range for the reheating temperature imposes some bounds on the models. As the last step, the result of trans-Planckian censorship conjecture for the model is considered where it is shown the constraint of TCC will be very strong and it could be used to applied limit on the brane tension.
