从LHC黑洞事件模拟得到的大额外维的边界

Bounds on large extra dimensions from the simulation of black hole events at the LHC

Shaoqi Hou, Benjamin Harms, Marco Cavaglia

摘要:

如果存在大的额外维度,普朗克尺度可能会低至TeV,而微观黑洞可能会在这个能量尺度的高能粒子碰撞中产生。我们在大型强子对撞机上模拟了微观黑洞的形成,并将模拟结果与最近的实验数据进行了比较。在实验数据中没有观测到黑洞事件,这使得我们能够为一些额外维度($3-6$)设定普朗克尺度和与微观黑洞形成相关的各种参数的下限。我们的分析设置下限的基本普朗克尺度范围从0.6 TeV到4.8 TeV的黑洞完全衰变成标准模型粒子和0.3 TeV到2.8 TeV的黑洞定居下来的残余物,这取决于最低允许的黑洞质量在形成。在95% C. L处排除了质量小于5. 2 - 6. 5 TeV(SM衰变)和2. 2 - 3. 4 TeV(残余)的黑洞的形成。我们的分析表明,与CMS结果的一致性和差异。

英文摘要:

If large extra dimensions exist, the Planck scale may be as low as a TeV and microscopic black holes may be produced in high-energy particle collisions at this energy scale. We simulate microscopic black hole formation at the Large Hadron Collider and compare the simulation results with recent experimental data by the Compact Muon Solenoid collaboration. The absence of observed black hole events in the experimental data allows us to set lower bounds on the Planck scale and various parameters related to microscopic black hole formation for a number ($3-6$) of extra dimensions. Our analysis sets lower bounds on the fundamental Planck scale ranging from 0.6 TeV to 4.8 TeV for black holes fully decaying into Standard Model particles and 0.3 TeV to 2.8 TeV for black holes settling down to a remnant, depending on the minimum allowed black hole mass at formation. Formation of black holes with mass less than 5.2 TeV to 6.5 TeV (SM decay) and 2.2 TeV to 3.4 TeV (remnant) is excluded at 95\% C.L. Our analysis shows consistency with and difference from the CMS results.
