重建Higgs共振τ对产生中的半不可见事件

Reconstructing semi-invisible events in resonant tau pair production from Higgs

Partha Konar, Abhaya Kumar Swain

摘要:

我们研究的可能性,利用约束质量变量,$M_{2Cons}$,在重建半不可见的事件起源于共振生产在大型强子对撞机。虽然这个建议是有效的任何类似的鹿角型生产机制,在这里,我们证明了潜在的有趣的情况下,当希格斯玻色子衰变成一对第三代$τ$轻子。在相对较大的汤川耦合的支撑下,LHC已经开始探索这种对的产生,以研究希格斯粒子在轻子扇区中的性质。τ的强子衰变的主要特征,与不可见的中微子相关联,增加了重建这些事件的难度。利用已经存在的希格斯质量约束,这种新方法提供了一个独特的事件重建,以及显着提高效率方面的现有方法。

英文摘要:

We study the possibility of utilising the constrained mass variable, $M_{2Cons}$, in reconstructing the semi-invisible events originated from a resonant production at the LHC. While this proposal is effective for any similar antler type production mechanism, here we demonstrate with potentially interesting scenario, when the Higgs boson decays into a pair of third generation $τ$ leptons. Buoyed with a relatively large Yukawa coupling, the LHC has already started exploring this pair production to investigate the properties of Higgs in the leptonic sector. Dominant signatures through hadronic decay of tau, associated with invisible neutrinos compound the difficulty in the reconstruction of such events. Exploiting the already existing Higgs mass bound, this new method provides a unique event reconstruction, together with a significant enhancement in terms of efficiency over the existing methods.
