Wolfenstein方案中的轻子味混合

Lepton flavor mixing in the Wolfenstein scheme

V. Gupta, G. Sánchez-Colón, S. Rajpoot, H-C. Wang

摘要:

我们模仿Wolfenstein夸克味混合方案来描述标准模型中的中微子振荡。我们确定的参数$λ$与实验测量值的混合元素负责大气中微子振荡。太阳中微子振荡的矩阵元和π z角分别与$λ^2$和$λ^3$成正比。利用目前世界上中微子的平均数据,我们导出了新方案中其他参数$A$、$ρ$和$η$的界.

英文摘要:

We mimic the Wolfenstein scheme of quark flavor mixing to describe neutrino oscillations in the standard model. We identify the parameter $λ$ with the experimentally measured value of the mixing element responsible for atmospheric neutrino oscillations. The matrix elements responsible for solar neutrino oscillations and the Chooz angle are taken to be proportional to $λ^2$ and $λ^3$, respectively. Using present world average data on neutrinos, we derive bounds on the other parameters $A$, $ρ$, and $η$, of the new scheme.
