Abstract

DUNE is a next-generation long-baseline neutrino oscillation experiment. It is expected to measure, with unprecedented precision, the atmospheric oscillation parameters, including the CP-violating phase δCP. Moreover, several studies have suggested that its unique features should allow DUNE to probe several new physics scenarios. In this work, we explore the performances of the DUNE far detector in constraining new physics if a high-energy neutrino flux is employed (HE-DUNE). We take into account three different scenarios: Lorentz Invariance Violation (LIV), Long-Range Forces (LRFs) and Large Extra Dimensions (LEDs). Our results show that HE-DUNE should be able to set bounds competitive to the current ones and, in particular, it can outperform the standard DUNE capabilities in constraining CPT-even LIV parameters and the compactification radius RED of the LED model.

利用深层地下中微子实验高能通量探索新物理:洛伦兹不变量违反、大超维空间和远距离力的情况
DUNE 是下一代长基线中微子振荡实验。它有望以前所未有的精度测量大气振荡参数,包括违反 CP 的阶段 δCP。此外,一些研究表明,DUNE 的独特功能应该能够探测到一些新的物理情景。在这项工作中,我们探讨了如果采用高能中微子通量(HE-DUNE),DUNE 远探测器在约束新物理学方面的性能。我们考虑了三种不同的情况:洛伦兹不变量违反(LIV)、长程力(LRFs)和大超维(LEDs)。我们的研究结果表明,HE-DUNE应该能够设定与当前模型具有竞争力的边界,特别是在约束CPT-even LIV参数和LED模型的压缩半径RED方面,它可以超越标准DUNE的能力。
