深地下中微子实验-- DUNE:中微子物理的精确时代

The Deep Underground Neutrino Experiment -- DUNE: the precision era of neutrino physics

Ernesto Kemp

摘要:

过去的十年对中微子物理学来说意义非凡。特别是,中微子味振荡现象已通过一系列独立测量牢固确立。中微子混合的所有参数现在都是已知的,我们有必要计划对这些最新进展所开启的新场景进行明智的探索。通过精确的测量,我们可以检验轻子扇区中的3-中微子范式、中微子质量等级和CP不对称性。未来的长基线实验被认为是加深我们对电弱相互作用认识的基本工具。深地下中微子实验- DUNE将在一个地下的大质量液氩时间投影室中探测来自费米实验室的宽带中微子束,其L/E约为$10^3$ km / GeV,以达到CP相测量和确定质量等级的良好灵敏度。远探测器的尺寸和深度也创造了一个很好的机会来寻找罕见的信号,如质子衰变,以研究重子数的破坏,以及超新星中微子爆发,将实验范围扩大到天体物理学和宇宙学中的相关影响。在本报告中,我们将讨论物理动机和DUNE项目的主要实验特征,以实现其科学目标。

英文摘要:

The last decade was remarkable for neutrino physics. In particular, the phenomenon of neutrino flavor oscillations has been firmly established by a series of independent measurements. All parameters of the neutrino mixing are now known and we have elements to plan a judicious exploration of new scenarios that are opened by these recent advances. With precise measurements, we can test the 3-neutrino paradigm, neutrino mass hierarchy and CP asymmetry in the lepton sector. The future long-baseline experiments are considered to be a fundamental tool to deepen our knowledge of electroweak interactions. The Deep Underground Neutrino Experiment -- DUNE will detect a broad-band neutrino beam from Fermilab in an underground massive Liquid Argon Time-Projection Chamber at an L/E of about $10^3$ km / GeV to reach good sensitivity for CP-phase measurements and the determination of the mass hierarchy. The dimensions and the depth of the Far Detector also create an excellent opportunity to look for rare signals like proton decay to study violation of baryonic number, as well as supernova neutrino bursts, broadening the scope of the experiment to astrophysics and associated impacts in cosmology. In this presentation, we will discuss the physics motivations and the main experimental features of the DUNE project required to reach its scientific goals.
