Findings

Non-standard couplings alter neutrino oscillation probabilities.

The model predicts measurable deviations in solar electron-neutrino fluxes.

Couplings could serve as probes for dark energy properties.

Abstract

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.
