摘要：

我们引入了一个有效的紫外截止$l$，对万亿级黑洞的产生截面进行了量子引力修正。我们发现，新的横截面接近通常的“黑盘”的形式在高能量，而他们显着不同的基本尺度附近的标准增加相对于$s$。我们表明，迄今为止不连续的阶梯函数用于代表的截面阈值可以逼真地模拟两个功能代表的传入和最终的部分子状态在高能碰撞。因此，具有碰撞能量的横截面的增长是$l$和空间维数$d$的唯一特征。与经典的黑盘结果相反，我们的横截面能够解释为什么黑洞在LHC实验中可能无法观察到，而它们仍然可以在超高能宇宙射线事件的范围内。

英文摘要：

We introduce analytical quantum gravity modifications of the production cross section for terascale black holes by employing an effective ultraviolet cut off $l$. We find the new cross sections approach the usual "black disk" form at high energy, while they differ significantly near the fundamental scale from the standard increase with respect to $s$. We show that the heretofore discontinuous step function used to represent the cross section threshold can realistically be modeled by two functions representing the incoming and final parton states in a high energy collision. The growth of the cross section with collision energy is thus a unique signature of $l$ and number of spatial dimensions $d$. Contrary to the classical black disk result, our cross section is able to explain why black holes might not be observable in LHC experiments while they could be still at the reach of ultra-high energy cosmic ray events.
