标题： Distinguishing Beyond-Standard Model Effects in Neutrino Oscillation

摘要： 我们系统地评估DUNE实验区分各种超出标准中微子振荡假设对组合的能力。 对于一对比较，我们评估统计分离度，其中一种假设扮演真实信号的角色，而另一种对应于测试信号。 正在审查的超出标准的中微子振荡假设包括中微子衰变（不可见和可见）、非标准相互作用、量子退相干以及等效原理的破坏。 当作为真实模型时，我们发现与其余假设相比，量子退相干或等效原理的破坏最容易区分。 此外，从我们的统计测试中，我们研究了测量的CP破坏相位$\delta_{CP}$相对于其真实值的潜在差异，这可能在给定比较中发生。 在我们的分析中，我们将$\delta_{CP}$的真实值取为$-90^\circ$和$180^\circ$。 值得注意的是，即使超出标准的中微子振荡假设情景在统计上无法区分，测量值仍可能与其真实值有显著偏差。 显示英文摘要

摘要： We systematically assess the DUNE experiment's ability to distinguish between various beyond-standard neutrino oscillation hypotheses pair combinations. For a pair comparison, we evaluate the statistical separation, where one hypothesis plays the role of the true signal while the other corresponds to the test signal. The beyond-standard neutrino oscillation hypotheses under scrutiny include neutrino decay (invisible and visible), non-standard interactions, quantum decoherence, and the violation of the equivalence principle. When taken as the true model, we found that either quantum decoherence or the violation of the equivalence principle are the easiest to differentiate compared to the rest of the hypotheses. Additionally, from our statistical test, we investigate potential discrepancies between the measured CP-violation phase $\delta_{CP}$ relative to its true value, which could occur for a given comparison. In our analysis, we will take the true values of $\delta_{CP}$ as $-90^\circ$ and $180^\circ$. Notably, even in cases where the beyond-standard neutrino oscillation hypotheses scenarios are statistically indistinguishable, the measured value can exhibit significant deviations from its true value.
