We consider black hole production at the CERN Large Hadron Collider (LHC) in a generic scenario with many extra dimensions where the standard model fields are confined to a brane. With approximately 20 dimensions the hierarchy problem is shown to be naturally solved without the need for large compactification radii. We find that in such a scenario the properties of black holes can be used to determine the number of extra dimensions, . In particular, we demonstrate that measurements of the decay distributions of such black holes at the LHC can determine if is significantly larger than 6 or 7 with high confidence and thus can probe one of the critical properties of string theory compactifications.
我们考虑欧洲核子研究中心大型强子对撞机（LHC）在一种具有多个额外维度的一般情形下产生黑洞的情况，其中标准模型场被限制在一个膜上。当有大约20个维度时，层级问题被证明可以自然地解决，而无需大的紧致化半径。我们发现，在这样的情形下，黑洞的性质可用于确定额外维度的数量。特别是，我们证明了在LHC对这类黑洞衰变分布的测量能够以高置信度确定该数量是否显著大于6或7，从而能够探测弦理论紧致化的一个关键性质。
