标题： High Energy Astrophysics Tests of Lorentz Invariance Violation

摘要： 多太电子伏特能谱的Mkn 501和其他BL Lac天体表现出高能截止，这种截止被预测是由于星系间湮灭相互作用的结果，主要是与红外光子的通量水平有关，该通量水平由各种天体物理观测确定。 在对这种星系间吸收进行校正后，这些能谱可以在同步自康普顿辐射模型的框架内得到解释。 Stecker和Glashow表明，通过电子-正电子对产生存在的这种湮灭对洛伦兹不变性破坏提出了强烈的约束。 这种约束对于某些量子引力和大额外维模型具有重要意义。 较小程度的洛伦兹不变性破坏对于理解超高能宇宙射线的能谱具有潜在的意义。 显示英文摘要

摘要： Multi-TeV spectra of Mkn 501 and other BL Lac objects exhibit the high energy cutoffs predicted to be the result of intergalactic annihilation interactions, primarily with IR photons having the flux level determined by various astrophysical observations. After correcting for such intergalactic absorption, these spectra can be explained within the framework of synchrotron self-Compton emission models. Stecker and Glashow have shown that the existence of this annihilation via electron-positron pair production puts strong constriants on Lorentz invariance violation. Such constriants have important implications for some quantum gravity and large extra dimension models. A much smaller amount of Lorentz invariance violation has potential implications for understanding the spectra of ultrahigh energy cosmic rays.
