我们能看到量子引力吗?光子在渐近安全方案

Can we see quantum gravity? Photons in the asymptotic-safety scenario

Babette Döbrich, Astrid Eichhorn

摘要:

在寻找引力的量子理论的过程中,找到量子引力效应的实验途径至关重要。由于这些预计是非常小的,在观测可及的尺度,这是有利的考虑过程中没有树级贡献的标准模型,如光子-光子散射。我们研究了这种情况下,在额外维度的设置中渐近安全的量子引力的含义,并指出,各种不久的将来光子对撞机设置,采用电子或μ子对撞机,甚至是纯粹的激光为基础的设置,可以提供第一个观测窗口到量子引力制度。

英文摘要:

In the search for a quantum theory of gravity it is crucial to find experimental access to quantum gravitational effects. Since these are expected to be very small at observationally accessible scales it is advantageous to consider processes with no tree-level contribution in the Standard Model, such as photon-photon scattering. We examine the implications of asymptotically safe quantum gravity in a setting with extra dimensions for this case, and point out that various near-future photon-collider setups, employing either electron or muon colliders, or even a purely laser-based setup, could provide a first observational window into the quantum gravity regime.
