Lilith:一种从希格斯测量中约束新物理的工具

Lilith: a tool for constraining new physics from Higgs measurements

Jeremy Bernon, Beranger Dumont

摘要:

观测到的质量约为125 GeV的希格斯玻色子的性质可以通过各种方式受到标准模型(SM)之外的新物理学的影响。针对希格斯玻色子玻色子的产生和衰变的不同组合的丰富实验结果使得评估非SM类希格斯玻色子玻色子与所有可用结果的兼容性成为一项重要任务。在本文中,我们提出了莉莉丝,一个新的公共工具,约束新的物理信号强度测量在LHC和Tevatron。Lilith是一个Python库,也可以用于C和C++/ROOT程序。希格斯的可能性是基于存储在一个易于扩展的XML数据库中的实验结果,并从用户输入进行评估,在减少耦合或信号强度方面以XML格式给出。Lilith的结果可以用来约束一大类新的物理场景。

英文摘要:

The properties of the observed Higgs boson with mass around 125 GeV can be affected in a variety of ways by new physics beyond the Standard Model (SM). The wealth of experimental results, targeting the different combinations for the production and decay of a Higgs boson, makes it a non-trivial task to assess the compatibility of a non-SM-like Higgs boson with all available results. In this paper we present Lilith, a new public tool for constraining new physics from signal strength measurements performed at the LHC and the Tevatron. Lilith is a Python library that can also be used in C and C++/ROOT programs. The Higgs likelihood is based on experimental results stored in an easily extensible XML database, and is evaluated from the user input, given in XML format in terms of reduced couplings or signal strengths. The results of Lilith can be used to constrain a wide class of new physics scenarios.
