摘要
We consider the sensitivity of future neutrino experiments in the low energy region, such as BOREXINO or HELLAZ, to a solar v(e) signal. We show that, if neutrino conversions within the Sun result in partial polarization of initial solar neutrino fluxes, then a new opportunity arises to observe the (v) over bar(e)'s and thus to probe the Majorana nature of the neutrinos. This is achieved by comparing the slopes of the energy dependence of the differential v(e)-scattering cross section for different neutrino conversion scenarios. We also show how the v(e) - (v) over bar(e) conversions may take place for low energy solar neutrinos while being unobservable at the Kamiokande and Super-Kamiokande experiment.
