准狄拉克中微子和太阳中微子数据

Quasi-Dirac neutrinos and solar neutrino data

F. Rossi-Torres, A. C. B. Machado, V. Pleitez

摘要:

我们提出了一个分析的太阳中微子数据的上下文中的准狄拉克中微子模型中的轻子混合矩阵在树的水平上给出的tribimaxial矩阵。当考虑辐射修正时,中微子振荡中出现了新的效应,如$ν_e \to ν_s$。这种振荡受到太阳中微子数据的限制。在我们的分析中,我们发现了两个自由参数$ε$和$m_1$的允许区域。辐射校正$ε$可以在$5\times 10^{-9}$至$10^{-6}$之间近似变化,并且计算的第四质量本征态$m_4$在2 $σ$能级处为0.01 eV至0.2 eV。这些结果与文献中的结果非常相似。

英文摘要:

We present an analysis of the solar neutrino data in the context of a quasi-Dirac neutrino model in which the lepton mixing matrix is given at tree level by the tribimaximal matrix. When radiative corrections are taken into account, new effects in neutrino oscillations, as $ν_e \to ν_s$, appear. This oscillation is constrained by the solar neutrino data. In our analysis, we have found an allowed region for our two free parameters $ε$ and $m_1$. The radiative correction, $ε$, can vary approximately from $5\times 10^{-9}$ to $10^{-6}$ and the calculated fourth mass eigenstate, $m_4$, 0.01 eV to 0.2 eV at 2$σ$ level. These results are very similar to the ones presented in the literature.
