轻子么正三角与真空和物质中具有CP破坏的中微子振荡的联系

Connecting Leptonic Unitarity Triangle to Neutrino Oscillation with CP Violation in Vacuum and in Matter

Hong-Jian He, Xun-Jie Xu

摘要:

轻子么正三角形(LUT)是几何描述中微子振荡中CP破坏的基本方法。在这项工作中,我们使用LUT提出了一个新的几何解释的真空振荡概率,并推导出一个紧凑的新的振荡公式,只有3个独立的参数相应的LUT。然后,我们系统地研究了具有CP破坏的中微子振荡几何描述中的物质效应。考虑到非平凡物质效应,我们利用查找表公式推导出了一个非常紧凑的新振荡公式。我们进一步证明了这个几何公式适用于物质中的中微子振荡,包括长基线实验T2K,MINOS,NOvA和DUNE。

英文摘要:

Leptonic unitarity triangle (LUT) provides fundamental means to geometrically describe CP violation in neutrino oscillation. In this work, we use LUT to present a new geometrical interpretation of the vacuum oscillation probability, and derive a compact new oscillation formula in terms of only 3 independent parameters of the corresponding LUT. Then, we systematically study matter effects in the geometrical formulation of neutrino oscillation with CP violation. Including nontrivial matter effects, we derive a very compact new oscillation formula by using the LUT formulation. We further demonstrate that this geometrical formula holds well for applications to neutrino oscillations in matter, including the long baseline experiments T2K, MINOS, NOvA, and DUNE.
