论文摘要
当人们对特殊相对论运动学的修改作为一个新的高能量量表的倒数时，我们分析了光子 - 光子相互作用中电子词素产生的运动学。在此扩展中，我们得出了该反应对第一阶的阈值能量的方程，包括由于能量摩托明管保护方程的修改而产生的效果。与Lorentz违反案例相反，发现几个TEV的顺序与与相对性原理兼容的修改相兼容的观察结果与非常高能量的宇宙伽玛射线兼容。
We analyze the kinematics of electron-positron production in a photon-photon interaction when one has a modification of the special relativistic kinematics as a power expansion in the inverse of a new high-energy scale. We derive the equation for the threshold energy of this reaction to first order in this expansion, including the effects due to a modification of the energy-momentum conservation equation. In contrast with the Lorentz invariance violation case, a scale of the order of a few TeV is found to be compatible with the observations of very high-energy cosmic gamma rays in the case of a modification compatible with the relativity principle.
