Résumé : In a left-right framework, we study the possibility of a light right-handed neutrino dark matter candidate. The most stringent constraints come from neutrino experiments on solar neutrino fluxes, suppressing the magnitude of the right-handed interactions. Despite this constraint we calculate the relic density avoiding over abundance thanks to a very low rehating temperature scenario. The possibility of explaining the Integral 511 keV line is also studied through a dark matter - baryon interaction. If the morphology seems to fit well the shape of the signal, the absolute flux is much too low compared to the experiment measurement. © 2006 American Institute of Physics.
