在大型强子对撞机上确定亚稳态Slepton的自旋
Determining Spins of Metastable Sleptons at the Large Hadron Collider
摘要:
本文研究了最小超引力参数空间中含有亚稳态slepton的模型。我们发现在这些情况下,需要确定slepton自旋的光度,并将我们的分析应用到两个基准模型。我们表明,在一个基准模型的自旋的slepton可以确定小于30 fb $^{-1}$的数据,而在其他模型的slepton自旋可以确定大约40 fb $^{-1}$的数据。我们展示了我们的分析可以应用到其他模型,并给出了一个自旋测定作为一个函数的slepton质量的光度估计。这种分析可以用来区分超对称性和额外维度。
英文摘要:
We investigate models in minimal supergravity parameter space which contain metastable sleptons. We find the luminosity required to determine the slepton spin in these scenarios, and apply our analysis to two benchmark models. We show that the spin of the slepton in one of the benchmark models can be determined with less than 30 fb$^{-1}$ of data, while the slepton spin in the other model can be determined with roughly 40 fb$^{-1}$ of data. We show how our analysis can be applied to other models, and give an estimate of the luminosity needed for a spin determination as a function of slepton mass. This analysis can be used to distinguish supersymmetry and extra dimensions.
