在对撞机实验中创造半经典黑洞并将它们保持在一根弦上
Creating semiclassical black holes in collider experiments and keeping them on a string
摘要：
我们认为，一个简单的修改TeV尺度的量子引力的情况下，允许生产的半经典黑洞在粒子碰撞在大型强子对撞机。关键的想法是，在具有大量额外维度的模型中，整体的引力强度可能高于我们生活的膜。这种情况的一个众所周知的例子是扭曲的额外维度的情况。即使碰撞的能量不足以在膜上产生一个黑洞，它也足以产生一个粒子，该粒子加速进入体块，达到trans-Planckian能量，并在那里产生一个大的黑洞。在我们考虑的一个具体模型中，黑洞是在粒子与它自己在轨道平面上的像碰撞时形成的。当所讨论的粒子带有一些标准模型规范电荷时，所产生的黑洞就通过一串规范通量附着在我们的膜上。对于一个四维观测者，这样的系统看起来像是一个长寿的带电态，由于黑洞的霍金蒸发，质量不断减少。这提供了一个独特的签名黑洞形成在我们的情况。
英文摘要：
We argue that a simple modification of the TeV scale quantum gravity scenario allows production of semiclassical black holes in particle collisions at the LHC. The key idea is that in models with large extra dimensions the strength of gravity in the bulk can be higher than on the brane where we live. A well-known example of this situation is the case of warped extra dimensions. Even if the energy of the collision is not sufficient to create a black hole on the brane, it may be enough to produce a particle which accelerates into the bulk up to trans-Planckian energy and creates a large black hole there. In a concrete model we consider, the black hole is formed in a collision of the particle with its own image at an orbifold plane. When the particle in question carries some Standard Model gauge charges the created black hole gets attached to our brane by a string of the gauge flux. For a 4-dimensional observer such system looks as a long-lived charged state with the mass continuously decreasing due to Hawking evaporation of the black hole. This provides a distinctive signature of black hole formation in our scenario.
