从普朗克结果看两零Majorana织构

Two-zero Majorana textures in the light of the Planck results

D. Meloni, A. Meroni, E. Peinado

摘要:

普朗克实验的最新结果对轻中微子质量之和提出了严格的限制,m1+m2+m3 < 0.23 eV(95%CL)。另一方面,二零马约拉纳质量矩阵纹理预测大气角和质量的总和之间的强相关性。我们利用Planck的结果表明,对于正常层次的情况下,具有消失(2,2)和(3,3)元素的纹理被排除在一个高的置信水平;此外,本发明还涉及一种用于该方法,我们强调,未来的测量的八分圆的大气混合角(或基于最近对中微子数据的拟合的一西格玛测定)将严重限制马约拉纳质量矩阵的可能结构。本文还讨论了正序和逆序的无中微子双β衰变的上述关联的意义。

英文摘要:

The recent results of the Planck experiment put a stringent constraint on the sum of the light neutrino masses, m1+m2+m3 < 0.23 eV (95 % CL). On the other hand, two-zero Majorana mass matrix textures predict strong correlations among the atmospheric angle and the sum of the masses. We use the Planck result to show that, for the normal hierarchy case, the texture with vanishing (2,2) and (3,3) elements is ruled out at a high confidence level; in addition, we emphasize that a future measurement of the octant of the atmospheric mixing angle (or the one sigma determination of it based on recent fit to neutrino data) will put severe constraint on the possible structure of the Majorana mass matrix. The implication of the above mentioned correlations for neutrinoless double beta-decay are also discussed, for both normal and inverted orderings.
