SUSY的原理:ATLAS和CMS高喷流多重性数据中的暗示性相关

Profumo di SUSY: Suggestive Correlations in the ATLAS and CMS High Jet Multiplicity Data

Tianjun Li, James A. Maxin, Dimitri V. Nanopoulos, Joel W. Walker

摘要:

我们不断积累的证据表明,CMS和ATLAS合作可能确实已经在大型强子对撞机(LHC)上记录了超对称事件。我们的分析是在一个唯象上非常有利的模型--无标度F-SU(5)模型中进行的,它代表了F-lipped SU(5)大统一理论(GUT)、两对由F理论推导出的TeV标度类矢量超对称多重态以及动态建立的无标度超引力边界条件的统一。我们记录了CMS和ATLAS观测到的第一个逆飞秒束之间的高度暗示性相关性,其中多喷流事件中诱人的过度,特别是那些具有9个或更多喷流的事件,通过F-SU(5)模型空间的精确蒙特卡罗模拟明确地解释了这些过度。这种密切的对应关系是优化的一个统一的高吉诺质量附近的M_{1/2} =518 GeV。我们通过外推预期的数据轮廓来补充这一分析,该数据轮廓将用五个积分亮度的逆飞秒来实现,正如预期在2011年结束时在LHC上观察到的那样。值得注意的是,我们发现,这种光度可能足以构成一个超对称发现的青睐的基准光谱。事实上,从日内瓦吹来的风可能已经充满了超对称的微妙香味。

英文摘要:

We present persistently amassing evidence that the CMS and ATLAS Collaborations may indeed be already registering supersymmetry events at the Large Hadron Collider (LHC). Our analysis is performed in the context of a highly phenomenologically favorable model named No-Scale F-SU(5), which represents the unification of the F-lipped SU(5) Grand Unified Theory (GUT), two pairs of hypothetical TeV-scale vector-like supersymmetric multiplets derived out of F-Theory, and the dynamically established boundary conditions of No-Scale supergravity. We document highly suggestive correlations between the first inverse femtobarn of observations by CMS and ATLAS, where seductive excesses in multijet events, particularly those with nine or more jets, are unambiguously accounted for by a precision Monte-Carlo simulation of the F-SU(5) model space. This intimate correspondence is optimized by a unified gaugino mass in the neighborhood of M_{1/2}=518 GeV. We supplement this analysis by extrapolating for the expected data profile to be realized with five inverse femtobarns of integrated luminosity, as expected to be observed at the LHC by the conclusion of 2011. Significantly, we find that this luminosity may be sufficient to constitute a SUSY discovery for the favored benchmark spectrum. Indeed, the winds wafting our way from Geneva may already be heavy with the delicate perfume of Supersymmetry.
