DUNE UK Production Project

LBNF/DUNE项目是高能粒子物理学的一项全球旗舰倡议，旨在解决有关宇宙起源和结构的关键问题。长基线中微子设施（LBNF）将是世界上最强的高能中微子束。它将从伊利诺斯州费米实验室向南达科他州的7万吨DUNE探测器发射中微子1300公里，以研究中微子振荡。DUNE将是第一个由美国主办的大规模实验，作为一个真正的国际项目。DUNE得到了来自美国和欧洲的全球粒子物理学界的广泛支持，对发展中国家的兴趣也越来越大; DUNE目前是一个由来自36个国家的1100多名合作者组成的科学合作组织，由英国全面领导。LBNF/DUNE将开展一项改变游戏规则的中微子物理学计划。它的最高科学目标是针对物理学中的重大问题：1）发现和测量中微子CP破坏。中微子和反中微子之间的这种微妙差异可能是宇宙中剩余物质的原因;2）精确的中微子物理学，包括质量等级的最终确定;3）寻找超越当前中微子振荡理解的新物理学; 4）观测来自银河系核心坍缩超新星的电子中微子爆发，提供中子星星和可能的黑洞形成的实时探测器; 5）寻找质子衰变，这是大多数新物理模型所预期的，但尚未观察到。英国正在为建造大规模DUNE远探测器做出重大贡献，通过英国大学、英国国家实验室和英国工业界之间的伙伴关系。在这项提案中，联合王国科学家要求提供资源，为这一全球科学项目建造探测器元件。

The LBNF/DUNE project is a global flagship initiative in high-energy particle physics that addresses key questions on the origin and structure of the universe. The long-baseline neutrino facility (LBNF) will be the world's most intense high-energy neutrino beam. It will fire neutrinos 1300 km from Fermilab in Illinois towards the 70,000 ton DUNE detector in South Dakota in order to study neutrino oscillations. DUNE will be the first large-scale US-hosted experiment run as a truly international project. DUNE has broad support from the global particle physics community in the US and Europe and with growing interest in developing countries; DUNE currently is a scientific collaboration of over 1100 collaborators from 36 nations, with overall UK leadership.LBNF/DUNE will undertake a game-changing programme of neutrino physics. Its highest-level scientific goals target big questions in physics: 1) Discovery and measurements of neutrino CP violation. This subtle difference between neutrinos and antineutrinos could be responsible for the remaining matter in the universe;2) Precision neutrino physics, including the definitive determination of the mass hierarchy;3) Search for new physics beyond the current understanding of neutrino oscillations;4) Observation of the electron neutrino burst from a galactic core-collapse supernova, providing a real-time probe of neutron star and possibly black hole formation;5) Search for proton decay, expected in most models of new physics, but not yet observed.The UK is making major contribution to the construction of the massive DUNE far detector, through a partnership between UK universities, UK national laboratories and UK industry. In this proposal UK scientists are requesting resources to construct detector elements for this global scientific project.
