摘要

摘要SHiP(寻找隐藏粒子)是欧洲核子研究中心 SPS 环上的一个新的通用实验,旨在寻找标准模型之外的众多理论提出的隐藏粒子,可能解释暗物质、中微子振荡和宇宙重子不对称。SHiP被宣布为零背景实验。实现这一目标的关键因素是μ介子屏蔽。一方面,它应该提供良好的背景抑制,另一方面,它又不能太重。本文介绍了利用贝叶斯优化法获得μ介子屏蔽配置的结果。这使得本底水平降低了 2.5 倍,而屏蔽的质量却保持在同一水平。

The SHiP Experiment: the Problem of Multidimensional Muon Shielding Optimization

Abstract

SHiP (Search for Hidden Particles) is a new general purpose experiment on the SPS ring at CERN, which aims to search for hidden particles proposed by numerous theories beyond the Standard Model, potentially explaining dark matter, neutrino oscillations, and baryon asymmetry of the universe. SHiP is declared as a zero background experiment. The key element to achieve this is the muon shielding. On the one hand, it should provide good background suppression, and on the other hand, it should not be too heavy. This paper presents the results of obtaining muon shielding configurations using Bayesian optimization. This made it possible to reduce the background level by 2.5 times while maintaining the mass of shielding at the same level.

期刊介绍: The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
