用ATLAS重建和鉴别强子Tau衰变

Reconstruction and Identification of Hadronic Tau Decays with ATLAS

Stan Lai, Anna Kaczmarska

摘要:

在许多希格斯玻色子和超对称性研究中,末态中τ轻子的存在是一个重要的特征。利用ATLAS探测器,强子衰变的τ轻子可以在很宽的横向能量范围内被重建。解释了强子衰变τ轻子的重建算法,并展示了τ轻子的识别性能。特别重要的是强子衰变τ轻子对QCD喷流压倒性的背景的歧视。

英文摘要:

The presence of tau leptons in the final state is an important signature in many Higgs boson and SUSY searches. With the ATLAS detector, hadronically decaying tau leptons can be reconstructed in a wide range of transverse energies. The reconstruction algorithm for hadronically decaying tau leptons is explained and the performance of tau lepton identification is shown. Particularly important is the discrimination of hadronically decaying tau leptons against overwhelming backgrounds from QCD jets.
