用地面中微子实验探索非标准中微子宇宙学

Probing nonstandard neutrino cosmology with terrestrial neutrino experiments

Akshay Ghalsasi, David McKeen, Ann E. Nelson

摘要:

中微子质量和轻中微子种类的数量可以在各种实验室实验中测试,也可以受到粒子天体物理学和精密宇宙学的约束。这些不同结果之间的冲突可能是中微子领域新物理学的标志。在本文中,我们探讨了调和的可能性,否则不一致的结果,在一个简单的模型包含一个轻标量场,产生质量变化的中微子(MaVaNs)。我们扩展了以前的工作,考虑中微子聚集的问题,中微子质量的额外贡献的影响,和和解的电子伏特质量无菌中微子与宇宙学。

英文摘要:

Neutrino masses and the number of light neutrino species can be tested in a variety of laboratory experiments and also can be constrained by particle astrophysics and precision cosmology. A conflict between these various results could be an indication of new physics in the neutrino sector. In this paper we explore the possibility for reconciliation of otherwise discrepant results in a simple model containing a light scalar field which produces Mass Varying Neutrinos (MaVaNs). We extend previous work on MaVaNs to consider issues of neutrino clumping, the effects of additional contributions to neutrino mass, and reconciliation of eV mass sterile neutrinos with cosmology.
