基于JUNO最新精确测量,验证了中微子质量平方差间的新颖依赖关系,实验值与理论预测高度一致,暗示中微子质量谱存在潜在对称性。
AI 中文摘要
在标准的三味中微子范式下,三个中微子质量平方差中有两个是独立的。最近,基于经验依据预测了这些振荡参数之间存在额外的依赖关系,其形式为$$\frac{\sqrt{\Delta m^2_{31}}+\sqrt{\Delta m^2_{21}}}{\sqrt{\Delta m^2_{31}}-\sqrt{\Delta m^2_{21}}}=\sqrt{2}.$$ JUNO合作组现已报告了迄今为止对$\Delta m^2_{21}$和$\Delta m^2_{31}$两者最精确的测量结果。我们证明该关系与实验数据高度吻合,实验数据给出$1.4143_{-0.0038}^{+0.0036}$,对应相对精度为$0.27\\%$。值得注意的是,中心值与预测值($\sqrt{2}\approx1.4142$)相差不到$0.03$个标准差。这为这一新颖约束提供了强有力的实验支持,从而表明存在一种支配中微子质量谱的潜在对称性,而非纯粹独立的参数。
英文摘要
In the standard three-flavor paradigm, two of the three neutrino mass-squared differences are independent. The existence of an additional dependence between these oscillation parameters was recently predicted on empirical grounds, taking the form $$\frac{\sqrt{Δm^2_{31}}+\sqrt{Δm^2_{21}}}{\sqrt{Δm^2_{31}}-\sqrt{Δm^2_{21}}}=\sqrt{2}.$$ The JUNO Collaboration has now reported the most precise measurements to date of both $Δm^2_{21}$ and $Δm^2_{31}$. We demonstrate that this relation is in excellent agreement with the experimental data, which yield $1.4143_{-0.0038}^{+0.0036}$ corresponding to a relative precision of $0.27\%$. Remarkably, the central value differs by less than $0.03$ standard deviations from the prediction ($\sqrt{2}\approx1.4142$). This provides strong experimental support for the novel constraint and thereby suggests an underlying symmetry governing the neutrino mass spectrum, rather than purely independent parameters.
