Abstract

Based on an analysis that considers the isotropic CPT-odd standard model extension (SME) coefficients, we find new constraints for them coming from a combined DUNE and ESSnuSB fit. Furthermore, we investigate the correlations of the standard oscillation parameters, the leptonic CP-violating phase, δCP, and the atmospheric mixing angle, sin2θ23, with respect to the SME coefficients (aL)T. The combination of DUNE and ESSnuSB may establish the strongest limit on the diagonal coefficient (aL)μμT compared to the existing limits in the literature. We also consider the possible effect of the SME coefficient (aL)Z on neutrino propagation and discuss how this can affect DUNE limits on the coefficient (aL)T found elsewhere.

结合DUNE和ESSnuSB分析约束标准模式扩展的各向同性CPT -odd系数

在考虑各向同性CPT-odd标准模型扩展系数的基础上，我们从DUNE和ESSnuSB的组合拟合中发现了新的约束条件。此外，我们还研究了标准振荡参数、轻子cp违反相位δCP和大气混合角sin2θ23与SME系数（aL）T的关系。与文献中已有的限制相比，DUNE与ESSnuSB的组合可能建立了对角系数(aL)μμT的最强限制。我们还考虑了SME系数（aL）Z对中微子传播的可能影响，并讨论了这如何影响DUNE对其他地方发现的系数（aL）T的限制。2025年由美国物理学会出版
