具有两个消失次项的中微子质量矩阵中的近极大大气混合

Near Maximal Atmospheric Mixing in Neutrino Mass Matrices with Two Vanishing Minors

S. Dev, Shivani Gupta, Radha Raman Gautam, Lal Singh

摘要:

在味基下,中微子质量矩阵中有7种两个子项消失的情况,它可以容纳包括最近的T2 K数据在内的现有中微子振荡数据。发现其中两种情况,即$B_5$和$B_6$,在大有效中微子质量的极限下,预言了接近最大的大气中微子混合。无论太阳能和反应堆混合角的值如何,该特征仍然存在。非零反应器混合角自然地容纳在这些纹理中。

英文摘要:

In the flavor basis there are seven cases of two vanishing minors in the neutrino mass matrix which can accommodate the present neutrino oscillation data including the recent T2K data. It is found that two of these cases, namely $B_5$ and $B_6$ predict near maximal atmospheric neutrino mixing in the limit of large effective neutrino mass. This feature remains irrespective of the values of solar and reactor mixing angles. A non-zero reactor mixing angle is naturally accommodated in these textures.
