T2HK和DUNE中物质密度的影响

Effect of Matter Density in T2HK and DUNE

Monojit Ghosh, Osamu Yasuda

摘要:

为不久的将来的长基线实验T2HK和DUNE确定CP相位,将需要精确测量振荡概率。然而,在确定这些振荡概率时,必须考虑地球密度的不确定性。因此,在这项研究中,我们更新了这些实验的个人灵敏度,以确定当前未知数在标准的三种口味的情况下,考虑到最新的配置和它们之间的互补性,同时考虑到密度的不确定性。我们的研究表明,这种不确定性对CP相位测定的精度有不可忽视的影响,特别是对于DUNE。

英文摘要:

CP phase determination for the near future long baseline experiments, T2HK and DUNE, will require precise measurements of the oscillation probabilities. However, the uncertainty in the Earth's density must be considered in determining these oscillation probabilities. Therefore, in this study, we update the individual sensitivities of these experiments for determining the current unknowns in the standard three flavor scenario considering the latest configuration and also the complementarity between them while considering the uncertainty in the density. Our study showed that this uncertainty has a non-negligible impact on the precision of the CP phase determination particularly for DUNE.
