Neutrino oscillation probabilities through the looking glass
摘要：
本文在长基线中微子实验的背景下，讨论了物质中中微子振荡几率的不同展开式。我们研究不同的精确和近似表达式的精度和计算效率。我们发现文献中使用的许多表达式对于下一代长基线实验来说不够精确，但其中一些表达式在保持相当简单的同时。本文的结果可以作为指导的现象学家和实验学家时，实现各种振荡表达式到他们的分析工具。
英文摘要：
In this paper we review different expansions for neutrino oscillation probabilities in matter in the context of long-baseline neutrino experiments. We examine the accuracy and computational efficiency of different exact and approximate expressions. We find that many of the expressions used in the literature are not precise enough for the next generation of long-baseline experiments, but several of them are while maintaining comparable simplicity. The results of this paper can be used as guidance to both phenomenologists and experimentalists when implementing the various oscillation expressions into their analysis tools.
