Neutrino Fluxes

The dynamic portrait of Yellowstone volcano activity in the form of detailed analysis of key parameters and in real time is presented. Some preliminary findings show that active volcanoes are energetically open systems with a strong influence of the external astrophysical component, primarily solar muon and neutrino fluxes. This should be taken into account when predicting their activity. The astrophysical component of activity may be one of the main mechanisms synchronizing the state of supervolcanoes. The astrophysical component of volcanic activity can exist in other volcanoes of the terrestrial planets of the Solar system, which also experience the synchronizing effects of the solar neutrino flux, that is, the planets of the Solar system can be found to have common rhythms of volcanic activity.

Evidence for variability in the solar output is briefly discussed. If the solar neutrino flux and the solar oscillation frequencies vary over a solar cycle this could indicate that the solar cycle has its origin in the solar core rather than be due to dynamo action in the solar convective zone.

There are compelling evidences for the existence of a fourth degree of freedom of neutrinos, i.e., sterile neutrino. In the recent studies the role of sterile component of neutrinos has been found to be crucial, not only in particle physics, but also in astrophysics and cosmology. This has been proposed to be one of the potential candidates of dark matter. In this work we investigate the updated solar neutrino data available from all the relevant experiments including Borexino and KamLAND solar phase in a model independent way and obtain bounds on the sterile neutrino component present in the solar neutrino flux. The mystery of the missing neutrinos is further deepening as subsequent experiments are coming up with their results. The energy spectrum of solar neutrinos, as predicted by Standard Solar Models (SSM), is seen by neutrino experiments at different parts as they are sensitive to various neutrino energy ranges. It is interesting to note that more than 98% of the calculated standard model solar neutrino flux lies below 1 MeV. Therefore, the study of low energy neutrinos can give us better understanding and the possibility of knowing about the presence of antineutrino and sterile neutrino components in solar neutrino flux. As such, this work becomes interesting as we include the data from medium energy (~1 MeV) experiments, i.e., Borexino and KamLAND solar phase. In our study we retrieve the bounds existing in literature and rather provide more stringent limits on sterile neutrino (νs) flux available in solar neutrino data.
