摘要：

理解和识别ditau喷流--由成对的tau粒子组成的喷流，可能至关重要，如果希格斯玻色子主要衰变为新的光标量，另一方面，衰变为tau对，甚至可能是必要的。正如在各种BSM模型中经常看到的那样，如NMSSM，希格斯门等，这些新态的亮度确保了它们的大横动量，并且因此确保了它们的衰变产物的共线性。我们表明，这些对象的非标准签名，这很容易被错过的标准分析技术，可以出色地利用在分析的基础上subjet可观的。当与额外的选择策略相结合时，这种分析甚至可以促进希格斯玻色子的早期发现。具体地说，可以用$S/\sqrt{B} \gtrsim 5$从$\mathcal {L} \simeq 12 fb^{-1}$的数据中找到一个轻的希格斯粒子。我们将所有这些观察到一个单一的歧视可能性，可以用于建设一个现实的和独立的ditau标签。

英文摘要：

Understanding and identifying ditau jets -- jets consisting of pairs of tau particles, can be of crucial importance and may even turn out to be a necessity if the Higgs boson decays dominantly to new light scalars which, on the other hand, decay to tau pairs. As often seen in various models of BSM such as in the NMSSM, Higgs portals etc., the lightness of these new states ensures their large transverse momenta and, as a consequence, the collinearity of their decay products. We show that the non-standard signatures of these objects, which can easily be missed by standard analysis techniques, can be superbly exploited in an analysis based on subjet observables. When combined with additional selection strategies, this analysis can even facilitate an early discovery of the Higgs boson. To be specific, a light Higgs can be found with $S/\sqrt{B} \gtrsim 5$ from $\mathcal {L} \simeq 12 fb^{-1}$ of data. We combine all these observables into a single discriminating likelihood that can be employed toward the construction of a realistic and standalone ditau tagger.
