论文摘要
希格斯通货膨胀率是最小的标准模型扩展，允许描述早期宇宙通货膨胀。由于它具有相对较低的截止量表，因此该模型被认为是一种有效的场理论，因此需要进一步的扩展为重新加热阶段的有效描述。我们提出了一种新颖的统一方法，即希格斯通货膨胀模型的单位化问题和紫外线完成问题，而没有引入新的大规模自由度。这种方法基于希格斯场动力学项的分析无限衍生物修饰。我们构建了原始希格斯通货膨胀模型的统一非本地紫外线完成，而通货膨胀阶段则在量子校正方面保持稳定。
Higgs inflation is known to be a minimal extension of the Standard Model allowing for the description of the early Universe inflation. This model is considered as an effective field theory since it has a relatively low cutoff scale, thus requiring further extensions to be a valid description of the reheating phase. We present a novel unified approach to the problem of unitarization and UV completion of the Higgs inflation model without introducing new massive degrees of freedom. This approach is based on an analytic infinite derivative modification of the Higgs field kinetic term. We construct a unitary non-local UV completion of the original Higgs inflation model while the inflationary stage is kept stable with respect to quantum corrections.
