论文摘要

在这项工作中,我们将ho红利夫希兹的缩放缩放为重写洛伦兹侵略的cpt-even电动力学中的高阶衍生物。洛伦兹不变性违规的可能性最初被量子重力能量表$ m _ {\ rm qg} $抑制,确实可以在某些中间和时间之间的各向异性范围内绕过,而在某些中等时段之间的各向异性均高于某些中等时段$λ_{\ rm hl} \ rm hl} \ ll m _ {为了测试该模型,我们使用了来自伽马射线爆发(GRB090510)事件之间的宇宙学时间延迟的观察结果。对于LifShitz关键指数的特定值,我们发现了$ M _ {\ rm QG} $的值的有趣下限。

In this work, we consider the Hořava-Lifshitz scaling to rewrite higher-order derivatives in Lorentz-violating CPT-even electrodynamics. The possibility of the Lorentz invariance violation being originally suppressed by the quantum gravity energy scale $M_{\rm QG}$, may be indeed circumvented in a scenario with anisotropy between space and time above certain intermediate energy scale $Λ_{\rm HL} \ll M_{\rm QG}$. To test the model, we have used observational results of a cosmological time delay between high and low energy photons from gamma ray bursts (GRB090510) event. For specific values of the Lifshitz critical exponent, we have found interesting lower bounds on the values of $M_{\rm QG}$.
