深度学习热门标签还是QCD的终结?

Deep-learning Top Taggers or The End of QCD?

Gregor Kasieczka, Tilman Plehn, Michael Russell, Torben Schell

摘要:

基于卷积神经网络的机器学习可用于研究LHC的喷流图像。在脂肪喷射机的顶部标记提供了一个定义良好的框架,以建立我们的DeepTop方法,并将其性能与基于QCD的顶部标记器进行比较。我们首先优化网络架构,以确定顶夸克的蒙特卡罗模拟的标准模型生产通道。使用标准的脂肪射流,然后比较其性能的多变量QCD为基础的顶部标记。我们发现,这两种方法导致相当的性能,建立卷积网络作为一个有前途的新方法,基于多变量假设的顶部标记。

英文摘要:

Machine learning based on convolutional neural networks can be used to study jet images from the LHC. Top tagging in fat jets offers a well-defined framework to establish our DeepTop approach and compare its performance to QCD-based top taggers. We first optimize a network architecture to identify top quarks in Monte Carlo simulations of the Standard Model production channel. Using standard fat jets we then compare its performance to a multivariate QCD-based top tagger. We find that both approaches lead to comparable performance, establishing convolutional networks as a promising new approach for multivariate hypothesis-based top tagging.
