Neutrino-Flavoured Sneutrino Dark Matter

Understand

A simple theory of supersymmetric dark matter (DM) naturally linked to neutrino flavour physics is studied.

• The DM sector comprises a spectrum of mixed lhd-rhd sneutrino states where both the sneutrino flavour structure and mass splittings are determined by the associated neutrino masses and mixings.
• Prospects for indirect detection from solar capture are good due to a large sneutrino-nucleon cross-section afforded by the inelastic splitting (solar capture limits exclude an explanation of DAMA/LIBRA).
• We find parameter regions where all heavier states will have decayed, leaving only one flavour mixture of sneutrino as the candidate DM.
