圈量子引力参数空间的唯象约束

Constraining the loop quantum gravity parameter space from phenomenology

Suddhasattwa Brahma, Michele Ronco

摘要:

量子引力理论的发展很少需要实验物理学的投入。在这封信中,我们采取了一个小步骤,纠正这一点,建立一个范式,将假定的量子校正,产生于规范量子引力(QG)理论,推导\textit{falsifiable}修改色散关系(MDRs)的变形闵可夫斯基时空中的粒子。这使我们能够通过\textit{testable, state-of-the-art}现象学预测来区分并在几个量子化选择之间进行选择。虽然这里给出了几个来自圈量子引力(LQG)的明确例子(例如使用的正则化方案或规范群的表示)来建立这一主张,但我们的框架更一般,能够解决LQG中的其他量子化模糊性以及其他类似QG方法所产生的模糊性。

英文摘要:

Development of quantum gravity theories rarely takes inputs from experimental physics. In this letter, we take a small step towards correcting this by establishing a paradigm for incorporating putative quantum corrections, arising from canonical quantum gravity (QG) theories, in deriving \textit{falsifiable} modified dispersion relations (MDRs) for particles on a deformed Minkowski space-time. This allows us to differentiate and, hopefully, pick between several quantization choices via \textit{testable, state-of-the-art} phenomenological predictions. Although a few explicit examples from loop quantum gravity (LQG) (such as the regularization scheme used or the representation of the gauge group) are shown here to establish the claim, our framework is more general and is capable of addressing other quantization ambiguities within LQG and also those arising from other similar QG approaches.
