在LHC的SUSY级联下通过Higgs玻色子产生探测非普适Gaugino质量:详细研究

Probing non-universal gaugino masses via Higgs boson production under SUSY cascades at the LHC: A detailed study

Priyotosh Bandyopadhyay

摘要:

在大型强子对撞机(LHC)中,超对称(SUSY)粒子的级联衰变可能是希格斯玻色子玻色子的丰富来源。在这项工作中,我们探索,在详细的模拟的帮助下,在超对称级联下的希格斯玻色子玻色子的生产中的作用,非普适的高根质量。分析是通过选择一组合适的基准点与非普适的Gaugino质量在相关的超对称性参数空间,然后将所得到的观察结果与相应的情况下具有普遍的关系。它表明,即使是在早期阶段的LHC运行与10 fb $^{-1}$的数据将能够看到,在有利的情况下,通过重建各种希格斯玻色子共振和比较它们的速率的非普适的高吉诺质量的印记。随着累积亮度的增加,指示将自然地在参数空间的较大区域上变得明显。

英文摘要:

Cascade decays of Supersymmetric (SUSY) particles are likely to be prolific sources of Higgs bosons at the Large Hadron Collider (LHC). In this work, we explore, with the help of detailed simulation, the role of non-universal gaugino masses in the production of the Higgs bosons under SUSY cascades. The analysis is carried out by choosing an appropriate set of benchmark points with non-universal gaugino masses in the relevant SUSY parameter space and then contrasting the resulting observations with the corresponding cases having universal relationship among the same. It is shown that even of data at an early phase of the LHC-run with 10 fb$^{-1}$ one would be able to see, under favourable situations, the imprint of non-universal gaugino masses by reconstructing various Higgs boson resonances and comparing their rates. With increased accumulated luminosities, the indications would naturally become distinct over a larger region of the parameter space.
