AI总结:

本研究开发了网页工具ADFilter,用基于深度无监督神经网络的自编码器处理对撞事件,可计算损失分布、两体不变质量与截面,能重新解读LHC结果以提升新物理寻找的排除限。

摘要:

我们开发了一款名为ADFilter的网页工具,它采用基于深度无监督神经网络的自编码器来处理对撞事件。这些自编码器在小部分对撞数据或标准模型(Standard Model)蒙特卡洛模拟数据上进行训练。该工具会计算输入事件的损失分布,帮助判定这些事件可被视为异常的程度;它还会计算自编码器处理前后的两体不变质量,以及截面。文中提供了实际应用示例,展示如何使用该工具重新解读现有大型强子对撞机(LHC)的结果,目标是显著提升排除限。

英文摘要:

A web-based tool called ADFilter was developed to process collision events using autoencoders based on a deep unsupervised neural network. The autoencoders are trained on a small fraction of either collision data or Standard Model Monte Carlo simulations. The tool calculates loss distributions for input events, helping to determine the degree to which the events can be considered anomalous. It also calculates two-body invariant masses both before and after the autoencoders, as well as cross sections. Real-life examples are provided to demonstrate how the tool can be used to reinterpret existing LHC results with the goal of significantly improving exclusion limits.
