A Modern Look at the Oscillation Physics Case for a Neutrino Factory

Peter B. Denton, Julia Gehrlein

AI总结:

本文重新评估中微子工厂方案,研究其到SURF的长基线配置并与DUNE、HK比较,分析束流优化、电荷鉴别及系统误差对三味振荡参数灵敏度的影响。

摘要:

下一代中微子振荡实验JUNO、DUNE和HK目前正在建设中,并将在未来十年及以后收集数据。由于目前没有已批准的计划用更先进的中微子振荡实验来跟进这一项目,我们在此考虑一个十多年前曾引起相当大兴趣的方案:中微子工厂。这类实验使用储存于跑道形结构中的μ子,其衰变特性被极其精确地刻画,从而降低系统不确定性,并提供更多的振荡道。这样一台装置也可能成为通向高能μ子对撞机计划的一步。我们考虑一种到SURF的长基线配置,使用DUNE远探测器或其改进型,并将预期的三味振荡参数灵敏度与DUNE和HK的预期结果进行比较。我们展示了最佳束流配置、电荷鉴别的影响、统计量与系统误差的作用,以及在不同DUNE与中微子工厂配置下对相关标准振荡参数的预期精度。

英文摘要:

The next generation of neutrino oscillation experiments, JUNO, DUNE, and HK, are under construction now and will collect data over the next decade and beyond. As there are no approved plans to follow up this program with more advanced neutrino oscillation experiments, we consider here one option that had gained considerable interest more than a decade ago: a neutrino factory. Such an experiment uses stored muons in a racetrack configuration with extremely well characterized decays reducing systematic uncertainties and providing for more oscillation channels. Such a machine could also be one step towards a high energy muon collider program. We consider a long-baseline configuration to SURF using the DUNE far detectors or modifications thereof, and compare the expected sensitivities of the three-flavor oscillation parameters to the anticipated results from DUNE and HK. We show optimal beam configurations, the impact of charge identification, the role of statistics and systematics, and the expected precision to the relevant standard oscillation parameters in different DUNE vs.~neutrino factory configurations.
