Description
The main motivation to search for solar flare neutrinos comes from their hadronic origin. Being inherent products of high-energy proton collisions with the chromosphere, they represent a direct probe of the protons accelerated towards the Chromosphere. Using a multi-messenger approach combining neutrinos and gamma rays, it is therefore possible to constrain the proton acceleration taking place in solar flares, especially the spectral index of the accelerated flux and its shape.
We present the results of the first search for GeV neutrinos emitted during solar flares carried out with the IceCube Neutrino Observatory. Originally designed to detect 10 GeV - TeV neutrinos, a new approach allowing to strongly lower the energy threshold of IceCube will be presented. We compare the results with theoretical estimates of the corresponding flux. We then discuss the prospects for the next solar flare cycles, for which KM3NeT, being currently deployed in the Mediterranean Sea, will be able to join IceCube in constraining/observing the solar flare neutrino flux. We present several analyses that can be performed using the KM3NeT detector in view of studying this flux. As a conclusion, we sketch the interest of combining KM3NeT and IceCube data in a solar flare neutrino search.
