量子关联与中微子质量简并问题

Quantum correlations and the neutrino mass degeneracy problem

Khushboo Dixit, Javid Naikoo, Subhashish Banerjee, Ashutosh Kumar Alok

摘要:

在三味中微子振荡的背景下,探讨了中微子系统的许多非经典性质。对与两个正在进行的实验NO $ν$ A和T2 K以及即将进行的实验DUNE相关的参数进行分析。不同的量子关联对中微子的质量等级问题很敏感。与无$ν$ A和T2 K实验相比,发现这种灵敏度在DUNE实验中更加突出。这可以归因于DUNE实验的大基线和高能量。此外,我们发现,为了探测这些相关性,中微子(反中微子)束应该是首选的,如果质量平方差$Δ_{31}$的符号原来是积极的(消极的)。

英文摘要:

Many facets of nonclassicality are probed in neutrino system in the context of three flavour neutrino oscillations. The analysis is carried out for parameters relevant to two ongoing experiments NO$ν$A and T2K, and also for the upcoming experiment DUNE. The various quantum correlations turn out to be sensitive to the mass-hierarchy problem in neutrinos. This sensitivity is found to be more prominent in DUNE experiment as compared to NO$ν$A and T2K experiments. This can be attributed to the large baseline and high energy of the DUNE experiment. Further, we find that to probe these correlations, the neutrino (antineutrino) beam should be preferred if the sign of mass square difference $Δ_{31}$ turns out to be positive (negative).
