论文摘要
在这项工作中，进一步开发了对中微子物质效应的重新归一化组方程（RGE）方法。我们得出了一组完整的微分方程，用于在存在轻型无菌中微子的情况下有效混合元件，质量和类似Jarlskog的不变性。混合元素以及类似jarlskog的不变性的演变是通过数值求解这些微分方程而获得的。我们计算长基线（LBL）实验中的陆地物质效应，以NOVA，T2K和DUNE为例。在三种培养物框架和四种培养物框架中，电子中性中微子的电子 - 中微子概率以及日夜不对称性也被评估为对RGE方法的进一步检查。
The renormalization-group equation (RGE) approach to neutrino matter effects is further developed in this work. We derive a complete set of differential equations for effective mixing elements, masses and Jarlskog-like invariants in presence of a light sterile neutrino. The evolutions of mixing elements as well as Jarlskog-like invariants are obtained by numerically solving these differential equations. We calculate terrestrial matter effects in long-baseline (LBL) experiments, taking NOvA, T2K and DUNE as examples. In both three-flavor and four-flavor frameworks, electron-neutrino survival probabilities as well as the day-night asymmetry of solar neutrino are also evaluated as a further examination of the RGE approach.
