AI 中文摘要
我们通过包含深度非弹性中微子散射，研究类DUNE装置对下夸克与奇异夸克之间味改变中性流相互作用的灵敏度。在针对狄拉克中微子和马约拉纳中微子的一般低能有效拉格朗日框架下，我们评估了针对CP优化和τ优化束流配置的预期灵敏度。相对于费米常数G_F定义的无量纲威尔逊系数的最强约束在近探测器处达到O(10⁻³)至O(10⁻²)，而远探测器处的约束则弱约一个数量级。当包含系统不确定性时，近探测器的灵敏度主要由本底率不确定性主导，而远探测器的灵敏度则主要受信号率不确定性限制。在远探测器处，预期约束对中微子质量顺序和狄拉克CP破坏相位δ_CP的依赖性主要局限于涉及电子味的系数。
英文摘要
We investigate the sensitivity of DUNE-like facilities to flavor-changing neutral-current interactions between down and strange quarks through inclusive deep-inelastic neutrino scattering. In the framework of a general low-energy effective Lagrangian for Dirac and Majorana neutrinos, we evaluate projected sensitivities for CP- and $τ$-optimized beam configurations. The strongest bounds on the dimensionless Wilson coefficients, defined relative to the Fermi constant $G_F$, reach $\mathcal{O}(10^{-3})\text{--}\mathcal{O}(10^{-2})$ at the near detector, whereas far-detector limits are roughly one order of magnitude weaker. When systematic uncertainties are included, the near-detector sensitivity is dominated by the background-rate uncertainty, while the far-detector sensitivity is limited primarily by the signal-rate uncertainty. At the far detector, the dependence of the projected bounds on the neutrino mass ordering and the Dirac CP-violating phase $δ_{\mathrm{CP}}$ is largely confined to coefficients involving the electron flavor.
