根据T2K $ν_e$外观数据,NO PDMATHAAB A的分级敏感性

Hierarchy sensitivity of NO$ν$A in light of T2K $ν_e$ appearance data

摘要:

T2 K实验的$ν_e$外观数据给出了层次- $δ_{CP}$参数空间中允许的参数的一瞥。在本文中,我们将探讨这些数据如何影响我们的期望,关于层次的灵敏度NO $ν$ A实验。对于层级和$δ_{CP}$的有利组合,NO $ν$ A的层级敏感性不受T2 K数据的添加的影响。对于不利的组合,没有$ν$ A数据给出简并解。在这些简并解中,T2 K数据更倾向于下半平面中的IH和$δ_{CP}$,而不是上半平面中的NH和$δ_{CP}$。因此,将T2 K数据添加到NO $ν$ A在下半平面中产生朝向IH和$δ_{CP}$的偏置,而不管真实组合是什么。

英文摘要:

The $ν_e$ appearance data of T2K experiment has given a glimpse of the allowed parameters in the hierarchy-$δ_{CP}$ parameter space. In this paper, we explore how this data affects our expectations regarding the hierarchy sensitivity of the NO$ν$A experiment. For the favourable combinations of hierarchy and $δ_{CP}$, the hierarchy sensitivity of NO$ν$A is unaffected by the addition of T2K data. For the unfavourable combinations, NO$ν$A data gives degenerate solutions. Among these degenerate solutions, T2K data prefers IH and $δ_{CP}$ in the lower half plane over NH and $δ_{CP}$ in the upper half plane. Hence, addition of the T2K data to NO$ν$A creates a bias towards IH and $δ_{CP}$ in the lower half plane irrespective of what the true combination is.
