论文摘要
几项研究已经致力于量子重力可能有明显地影响从遥远的天体物理来源传播到我们的望远镜的颗粒的相对论运动学，但是迄今为止，相关的文献仅专注于场景的子类，以使量子 - 严格性效应效果与（摩cococopopic）相关。假定，曲率触发的量子重力效应的现象学可能是由于双重抑制而成为死胡同：由于特征量子 - 重力长度尺度和曲率较小的特征量子量子重度长度的较小。鉴于一些最近的量子重力研究，这种情况变得越来越不令人满意，这些研究提供了以下事实：为了具有新颖的相对论特性，可能需要弯曲的存在。我们在这里分析了曲率诱导的量子重力效应的明确场景，并表明曲率的较小性不会对现象学构成挑战，因为它是由相关现象学研究中考虑的粒子所传播的较大距离所补偿的。我们还观察到，从遥远的天体物理来源传播到望远镜的颗粒的当前数据情况，虽然尚无定论，但与曲率无关的效应相比，对我们的曲率诱导的效应提供了更多的鼓励，这些效应已经研究到了。
Several studies have been devoted to the possibility that quantum gravity might tangibly affect relativistic kinematics for particles propagating from distant astrophysical sources to our telescopes, but the relevant literature has so far focused exclusively on a subclass of scenarios such that the quantum-gravity effects are independent of (macroscopic) curvature. It was assumed that a phenomenology for quantum-gravity effects that are triggered by curvature might be a dead end because of a double suppression: by the smallness of the characteristic quantum-gravity length scale and by the smallness of curvature. This state of affairs is becoming increasingly unsatisfactory in light of some recent quantum-gravity studies providing evidence of the fact that the presence of curvature might be required in order to have the novel relativistic properties. We here analyze an explicit scenario for curvature-induced quantum-gravity effects, and show that the smallness of curvature does not pose a challenge for phenomenology since it is compensated by the large distances traveled by the particles considered in the relevant phenomenological studies. We also observe that the present data situation for particles propagating from distant astrophysical sources to our telescopes, while inconclusive, provides more encouragement for our curvature-induced effects than for the curvature-independent effects that were so far studied.
