LHC黑洞的最高产量

Top Production from Black Holes at the LHC

M. Mohammadi Najafabadi, S. Paktinat Mehdiabadi

摘要:

在大额外维和低量子引力尺度(TeV)的理论中,人们期望在LHC中质子-质子碰撞中产生TeV尺度的黑洞,其质心能量为14 TeV。由于黑洞的温度可以在1 TeV左右,因此预计它们通过霍金辐射产生顶夸克。在粒子物理学的标准模型中,顶夸克是通过$t\bar{t}$对中的强相互作用或通过单个的电弱相互作用产生的。因此,黑洞可以成为顶夸克产生的新来源。本文给出了LHC上黑洞产生顶夸克的总截面和横动量分布。我们发现,从黑洞的顶夸克往往驻留在非常高的横向动量区,所以它可以是一个非常有用的签名的黑洞在大型强子对撞机。

英文摘要:

In theories with large extra dimension and with low quantum gravity scale near a TeV, it is expected that TeV-scale black holes to be produced in proton-proton collisions at the LHC with the center of mass energy of 14 TeV. Since the black holes temperature can be around 1 TeV, top quark production is expected from them via Hawking radiation. Within the Standard Model of particle physics top quarks are produced via strong interaction in $t\bar{t}$ pairs or via electroweak interaction singly. Therefore, black holes can be the new source of top quark production. In this article we present the total cross sections and transverse momentum distributions of top quark production from black holes at the LHC. We find that the top quarks from black holes tend to reside at very high transverse momentum region so it can be a very useful signature for the black holes at the LHC.
