TeV-gravity黑洞事件中的角关联

Angular correlations in TeV-gravity black hole events

Marco O. P. Sampaio

摘要:

我们在LHC的高维黑洞事件场景中进行了部分子水平的角关联研究。首先,我们讨论了一些特点的角谱在高能量极限使用几何光学近似。这使我们能够恢复霍金通量的高能量极限。然后,我们使用完整的霍金角通量的膜上,一个单一的旋转Myers-Perry黑洞,以激发各种角度可观的建设,以最大限度地提高由于旋转的角度不对称性。这是最后适应的部分子级模拟使用CHARYBDIS 2发生器。我们探讨两种类型的变量的基础上:轴重建和两粒子角动量。我们发现能量削减有可能帮助确定在14 TeV运行期间在LHC的半经典旋转黑洞事件中旋转的影响,特别是对于自旋为1的粒子。

英文摘要:

We perform a parton level study of angular correlations, in higher dimensional black hole events scenarios at the LHC. We start by discussing some features of the angular spectrum in the high energy limit using the geometrical optics approximation. This allows us to recover the high energy limit of the Hawking fluxes. Then we use the full Hawking angular fluxes on the brane, for a singly rotating Myers-Perry black hole, to motivate the construction of various angular observables as to maximise the angular asymmetries due to rotation. This is finally adapted to a parton level simulation using the CHARYBDIS2 generator. We explore two types of variables based on: axis reconstruction and two-particle angular correlators. We find energy cuts which have the potential to help identify the effects of rotation in semi-classical rotating black hole events at the LHC during the 14 TeV run, especially for spin-1 particles.
