用T2HKK和DUNE中的太阳中微子张力检验PDKEEPAAA

Testing NSI suggested by the solar neutrino tension in T2HKK and DUNE

Monojit Ghosh, Osamu Yasuda

摘要:

结果表明,在中微子传播过程中引入非标准的依赖于味道的相互作用(NSI),可以解决从太阳中微子中得到的质量平方差与通过KamLAND实验得到的质量平方差之间的紧张关系。在这项研究中,我们讨论了使用未来的长基线中微子实验T2HKK和DUNE测试这样一个假设的可能性。假设NSI不存在,我们提供了($ε_D$,$ε_N$)平面内的排除区域,其中$ε_D$和$ε_N$是用NSI进行的太阳中微子分析中出现的参数。我们发现,从太阳中微子和KamLAND数据(一个特定的耦合到夸克的全球分析)的最佳拟合值可以测试在10个以上的$σ$(3 $σ$),这两个实验的大部分参数空间。

英文摘要:

It was shown that the tension between the mass-squared differences obtained from solar neutrinos and those acquired through KamLAND experiments may be solved by the introduction of a non-standard flavor-dependent interaction (NSI) in neutrino propagation. In this study, we discuss the possibility of testing such a hypothesis using the future long-baseline neutrino experiments T2HKK and DUNE. Assuming that the NSI does not exist, we provide the excluded region within the ($ε_D$, $ε_N$) plane, where $ε_D$ and $ε_N$ are the parameters appearing in the solar neutrino analysis conducted with the NSI. We find that the best-fit value from the solar neutrino and KamLAND data (global analysis of a particular coupling to quarks) can be tested at more than 10$σ$ (3$σ$) by these two experiments for most of the parameter space.
