黑洞气簇中的QCD和自旋效应

QCD and spin effects in black hole airshowers

Marco Cavaglia, Arunava Roy

摘要:

在具有较大额外维度的模型中,黑洞可能是在高能粒子碰撞中产生的。我们重新讨论了超高能宇宙射线在大范围空气簇射中形成黑洞的物理过程,重点讨论了碰撞QCD和黑洞发射率效应。本文给出了旋转黑洞的新结果。蒙特卡罗模拟表明,QCD效应和黑洞自旋在空气簇射中没有产生可观测的信号。这些结果进一步证实了黑洞诱导的空气簇射的主要特征并不依赖于微观黑洞模型的精细细节。

英文摘要:

In models with large extra dimensions, black holes may be produced in high-energy particle collisions. We revisit the physics of black hole formation in extensive airshowers from ultrahigh-energy cosmic rays, focusing on collisional QCD and black hole emissivity effects. New results for rotating black holes are presented. Monte Carlo simulations show that QCD effects and black hole spin produce no observable signatures in airshowers. These results further confirm that the main characteristics of black hole-induced airshowers do not depend on the fine details of micro black hole models.
