论文摘要
我们研究的最终动机是在标准模型(BSM)之外寻找物理学的迹象。我们调查不同的喷气聚类技术是否或多或少适合特定最终感兴趣的状态。特别是,我们对从希格斯玻色(Higgs Boson)等标准模型的衰减链中出现的完全耐达的最终状态感兴趣。我们表明,从IT选择多射流最终状态和重建Higgs玻色子的不变质量的能力在很大程度上取决于削减措施,分辨率参数和重建算法的选择及其设置。因此,我们指出后者的最佳选择是为了建立BSM信号等基准。然后,我们重复了剧烈的Higgs玻色子级联成两个Sm样希格斯状态的练习,从而获得了相似的结果。
The ultimate motivation of our study is to look for signs of physics beyond the Standard Model (BSM). We investigate whether different jet clustering techniques might be more or less suited to the particular final states of interest. In particular, we are interested in fully hadronic final states emerging from the decay chain of the Standard Model like Higgs boson into pairs of light Higgs states, the latter in turn decaying into bottom-anti bottom pairs. We show that, the ability of selecting the multi-jet final state and to reconstruct invariant masses of the Higgs bosons from it depend strongly on the choice of acceptance cuts, resolution parameters and reconstruction algorithm as well as its settings. Hence, we indicate the optimal choice of the latter for the purpose of establishing such a benchmark as a BSM signal. We then repeat the exercise for a heavy Higgs boson cascading into two SM-like Higgs states, obtaining similar results.
