论文摘要

新的物理模型构建需要大量的交叉检查,以应对可用的实验结果。特别是,在许多型号中都可以找到新的中性,无色,旋转1玻色子$ z'$。我们在这项工作中介绍了一个新的易于使用的软件z'-enpplorer,该软件将$ z'$型号探究到LHC的所有可用衰减频道。该程序仔细检查了模型的参数空间,以确定仍允许的哪个部分,该零件应很快探索,哪个通道在每个参数空间的每个区域中都是最敏感的。用户不需要实现模型或运行任何蒙特卡洛模拟,而只需要使用$ z'$质量及其耦合到标准模型粒子即可。我们描述了Z'-explorer后端,并提供了从其前端使用它的说明,同时将其应用于各种$ z'$型号。特别是,我们在顺序标准模型,B-l $ Z'$以及简化的两个扇区或扭曲/复合模型中显示了Z'-explorer应用程序和实用程序。该程序的输出凝结了模型特征的现象学,实验技术和每个通道中的搜索策略在丰富的结果中。我们发现,该软件的引人注目的附加组件是包括衰减通道之间的相关性,低能量物理结果和暗物质搜索。该软件已准备好使用,可用于社区的修改,改进和更新。

New Physics model building requires a vast number of cross-checks against available experimental results. In particular, new neutral, colorless, spin-1 bosons $Z'$, can be found in many models. We introduce in this work a new easy-to-use software Z'-explorer which probes $Z'$ models to all available decay channels at LHC. This program scrutinizes the parameter space of the model to determine which part is still allowed, which is to be shortly explored, and which channel is the most sensitive in each region of parameter space. User does not need to implement the model nor run any Monte Carlo simulation, but instead just needs to use the $Z'$ mass and its couplings to Standard Model particles. We describe Z'-explorer backend and provide instructions to use it from its frontend, while applying it to a variety of $Z'$ models. In particular we show Z'-explorer application and utility in a sequential Standard Model, a B-L $Z'$ and a simplified two-sector or Warped/Composite model. The output of the program condenses the phenomenology of the model features, the experimental techniques and the search strategies in each channel in an enriching outcome. We find that compelling add-ons to the software would be to include correlation between decay channels, low-energy physics results, and Dark Matter searches. The software is open-source ready to use, and available for modifications, improvements and updates by the community.
