Neutrino magnetic moments and low-energy solar neutrino-electron scattering experiments - art. no. 013004

The scattering of solar neutrinos on electrons is sensitive to the neutrino magnetic moments through an interference of electromagnetic and weak ampli tudes in the cross section. We show that future low-energy solar neutrino e xperiments with good angular resolution can be sensitive to the resulting a zimuthal asymmetries in event number and should provide useful information on non-standard neutrino properties such as magnetic moments. We compare as ymmetries expected at Hellaz (mainly pp neutrinos) with those at the Kamiok ande and Super-Kamiokande experiments (boron neutrinos), both for the case of Dirac and Majorana neutrinos and discuss the advantages of low energy ex periments. Potentially interesting information on the solar magnetic fields may be accessible.
