标题： New Matter Effects in Neutrino Oscillation Experiments

摘要： 一种由轻标量粒子介导的新力对中微子振荡实验的后果进行了考虑。 这种力可能导致中微子质量与混合，其物质依赖性比MSW效应显著得多。 我们考虑了这种新力对从振荡实验中得出的限制的影响，并检查了对中微子模型的约束是如何改变的。 需要重新分析中微子数据，以及系统地探索大物质效应的新实验，以直接探测标准模型之外的这种物理现象。 显示英文摘要

摘要： Consequences of a new force mediated by a light scalar particle for neutrino oscillation experiments are considered. Such a force could give rise to neutrino masses and mixings whose matter dependence is much more significant than the MSW effect. We consider the effects of such a new force on the limits derived from oscillation experiments, and examine how the constraints on neutrino models are altered. Re-analysis of neutrino data, as well as new experiments in which large matter effects are systematically explored, is required to directly probe such physics beyond the standard model.
