| contents | Dark matter (DM) particles gravitationally captured by the Sun can accumulate in its core and subsequently annihilate, producing neutrino fluxes that may be detectable on Earth. The intensity of these fluxes is highly sensitive to the properties of the underlying DM model, especially when the DM candidate is a scalar particle originating from spontaneous or non-linear symmetry breaking mechanisms. In this work, we explore the potential of solar neutrino fluxes to distinguish between the Standard Model extended by a scalar singlet and the non-linear Higgs portal scenarios in the context of a future DM discovery. We compute the expected neutrino fluxes within the regions of parameter space consistent with both relic density and current direct detection limits. Our results show that the non-linear model predicts neutrino fluxes that are systematically larger than those of the linear case, typically by at least one order of magnitude, and up to six orders of magnitude for DM masses around 1 TeV. These findings suggest that solar neutrino observations could provide a valuable probe to discriminate between these competing dark matter frameworks. |
