摘要:

如果新物理能标在中微子振荡实验的能量范围内,它可能导致产生和探测过程之间以及不同实验之间的重整化群(RG)运行效应。因此,可以利用多个中微子振荡实验来区分多个RG运行参数。我们在一般模型无关的意义上研究了这一效应,针对即将进行的DUNE-ND、JUNO-TAO和FASER$\ u$2实验(它们覆盖了广泛的中微子能量范围和许多不同的味组合)中的各种味结构。我们发现,这些实验的组合对新物理的运行效应具有强灵敏度,尤其是解决非平凡简并问题的可能性。

英文摘要:

If the new physics scale is within the energy scale of neutrino oscillation experiments, it may lead to a renormalization group (RG) running effect between the production and detection processes as well as between different experiments. It is then possible to use multiple neutrino oscillation experiments to disentangle the multiple RG running parameters. We investigate this effect in a general model-independent sense for a variety of flavor structures in the context of upcoming experiments DUNE-ND, JUNO-TAO, and FASER$ν$2 that span a large range in neutrino energies and many different flavor combinations. We find strong sensitivity to the running effects of new physics with combination of these experiments, especially the possibility of addressing the non-trivial degeneracies.
