Scientific paper

We report on a model in which the right-handed sneutrino is a viable WIMP dark matter candidate [1]. It consists on an extension of the MSSM with a singlet S with coupling SH1H2 in order to solve the μ problem as in the NMSSM, and right-handed neutrinos N with couplings SNN in order to generate dynamically electroweak-scale Majorana masses. Through the direct coupling to the singlet, the sneutrino can not only be thermally produced in the right amount but also have a large enough scattering cross section with nuclei to detect it directly in near future, in contrast with most of other right-handed sneutrino dark matter models.
