摘要:

我们提出了一个算法重建事件中的希格斯玻色子衰变为一对τ轻子的希格斯质量。该算法是基于矩阵元(ME)技术,并实现了相对分辨率的希格斯玻色子的质量通常为15- 20%。该算法的前一个版本已被用于分析的希格斯玻色子生产的CMS合作在大型强子对撞机运行1。该算法进行了详细描述,其性能模拟事件进行评估。发展的技术来处理tau衰变的ME形式主义是本文的一个重要成果。

英文摘要:

We present an algorithm for the reconstruction of the Higgs mass in events with Higgs bosons decaying into a pair of tau leptons. The algorithm is based on matrix element (ME) techniques and achieves a relative resolution on the Higgs boson mass of typically 15-20%. A previous version of the algorithm has been used in analyses of Higgs boson production performed by the CMS collaboration during LHC Run 1. The algorithm is described in detail and its performance on simulated events is assessed. The development of techniques to handle tau decays in the ME formalism represents an important result of this paper.
