摘要:

我们调查可能的签名黑洞事件在大型强子对撞机的假设,这些对象不会完全蒸发,但留下一个稳定的残余。为了定义一个参考方案的目的,我们采用了公开可用的Monte Carlo生成器CHARYBDIS 2,其中残余物的行为主要取决于运动学约束和一些量子数的守恒,如重子电荷。我们的研究结果表明,电中性的残余物是非常有利的,一个显着更大的量失踪的横向动量是预期相对于完全衰变的情况下。

英文摘要:

We investigate possible signatures of black hole events at the LHC in the hypothesis that such objects will not evaporate completely, but leave a stable remnant. For the purpose of defining a reference scenario, we have employed the publicly available Monte Carlo generator CHARYBDIS2, in which the remnant's behavior is mostly determined by kinematic constraints and conservation of some quantum numbers, such as the baryon charge. Our findings show that electrically neutral remnants are highly favored and a significantly larger amount of missing transverse momentum is to be expected with respect to the case of complete decay.
