摘要
我们研究了在运动学由 D=4 庞加莱代数的 κ-变形描述的假设下，硬光子和软光子碰撞产生电子-正电子对的过程。我们强调了这一分析对于理解来自马卡良 501 的多 TeV 光子令人困惑的观测结果的相关性。我们发现 κ-变形对阈值以上的过程有显著影响，而与此前的一项研究一致，我们发现阈值条件不存在首阶变形。

LaTeX, 9 pages. Amelino-Camelia joined the collaboration. We improved the analysis in many ways; in particular, we now find full agreement witha previous study, by Amelino-Camelia and Piran, of threshold particle-production. We also present an analysis of processes above threshold, obtaining results that could provide an explanation for puzzling observations of multi-TeV photons Markarian501
