Regarding the proximity of dark energy scale and neutrino mass, one can get new insight into the probe signatures of vector field dark energy component on neutrino flavor conversion. A vector field is assumed to be conformally coupled to various matter components through a screening paradigm. We show how the oscillation probabilities evolve differently with a finite-size matter density like the Sun for different values of relevant model parameters. Considering existing neutrino flavor conversion data, we point out how this non-standard coupling affects neutrino fluxes, and also, we compute the discrepancy in the total flux of solar electron-neutrinos.

矢量场非标准耦合对太阳中微子通量的印记


关于暗能量尺度和中微子质量的接近程度，我们可以对矢量场暗能量分量对中微子风味转换的探测特征有新的认识。假设矢量场通过筛选范式与各种物质分量共形耦合。我们展示了对于相关模型参数的不同值，振荡概率如何随着有限尺寸的物质密度（如太阳）而以不同的方式演变。考虑到现有的中微子风味转换数据，我们指出了这种非标准耦合如何影响中微子通量，并且还计算了太阳电子-中微子总通量的差异。
