论文摘要
循环量子重力的作用还包括HOLST项和/或Nieh-Yan项，除了RICCI标量。这些术语预计将非最低限度地与希格斯息息。因此，Holst和Nieh-Yan术语有助于经典的运动方程，并且它们可以对通货膨胀产生重大影响。 我们在非最小耦合的参数空间中得出通货膨胀预测，包括非最小耦合项至维度4。即使在RICCI标量的零或负耦合的情况下，成功的通货膨胀也是可能的。值得注意的是，仅由非最小耦合的HOLST期限支持的通货膨胀与原始度量公式高原Higgs通货膨胀几乎具有相同的可观察力。仅凭非最终耦合的Nieh-Yan术语不能成功通货膨胀。当考虑这三个术语时，光谱指数和张量比比率的预测几乎涵盖了即将进行的实验探测的整个范围。对于频谱指数的运行而言，这并不是正确的，并且许多情况是高度调整的。
The action of loop quantum gravity includes the Holst term and/or the Nieh-Yan term in addition to the Ricci scalar. These terms are expected to couple non-minimally to the Higgs. Thus the Holst and Nieh-Yan terms contribute to the classical equations of motion, and they can have a significant impact on inflation. We derive inflationary predictions in the parameter space of the non-minimal couplings, including non-minimally coupled terms up to dimension 4. Successful inflation is possible even with zero or negative coupling of the Ricci scalar. Notably, inflation supported by the non-minimally coupled Holst term alone gives almost the same observables as the original metric formulation plateau Higgs inflation. A non-minimally coupled Nieh-Yan term alone cannot give successful inflation. When all three terms are considered, the predictions for the spectral index and tensor-to-scalar ratio span almost the whole range probed by upcoming experiments. This is not true for the running of the spectral index, and many cases are highly tuned.
