Abstract

SHiP (Search for Hidden Particles) is a new general-purpose experiment at the SPS ring at CERN, aimed at searching for hidden particles proposed by numerous theories beyond the Standard Model. An important element of the experiment is muon shield. On one hand, it must provide good background suppression, and on the other hand, it should not be too heavy. This work presents the results of obtaining muon shield configurations using Bayesian optimization with several types of surrogates. This allowed for effective global multidimensional optimization in a 42-dimensional space and reduced the muon flux by 2.5 times while maintaining the original mass of the shield.

Abstract Image

SHiP(寻找隐藏粒子)是欧洲核子研究中心 SPS 环上的一项新的通用实验,旨在寻找标准模型之外的众多理论所提出的隐藏粒子。该实验的一个重要元素是μ介子屏蔽。一方面,它必须提供良好的背景抑制,另一方面,它又不能太重。这项工作展示了利用贝叶斯优化方法获得μ介子屏蔽配置的结果。这使得在 42 维空间中进行有效的全局多维优化成为可能,并在保持μ介子屏蔽原有质量的情况下将μ介子通量降低了 2.5 倍。
