MaVaN作为太阳中唯一中微子味转换机制的可能方案

Possible scenario for MaVaN's as the only neutrino flavor conversion mechanism in the Sun

Pedro Cunha de Holanda

摘要:

质量变化的中微子机制被提出来将中微子质量尺度与暗能量联系起来,解决巧合问题。在某些情况下,这个质量可以表现出对中微子所感受到的重子密度的依赖性,从而产生一个同时依赖于中微子和重子密度的有效中微子质量。在这篇文章中,我们探讨了中微子有效质量是中微子振荡实验中唯一的味转换机制的可能性。我们提出了一个参数化的环境对中微子质量的影响,产生正确的味道转换概率的太阳能和地球上的中微子实验。

英文摘要:

Mass Varying neutrino mechanisms were proposed to link the neutrino mass scale with dark energy, addressing the coincidence problem. In some scenarios this mass can present a dependence on the baryonic density felt by neutrinos, creating an effective neutrino mass that depends both on the neutrino and baryonic densities. In this article we investigate the possibility that a neutrino effective mass is the only flavour conversion mechanism acting in neutrino oscillation experiments. We present a parameterization on the environmental effects on neutrino mass that produces the right flavour conversion probabilities for solar and terrestrial neutrinos experiments.
