Scientific paper

The identity of dark matter has not been solved up to this date, a problem that became the main topic of this conference. There are many theoretical candidates for dark matter particle, including gravitino from supergravity models. For gravitino dark matter scenario, the phenomenology depends much on what the next lightest supersymmetric particle (NLSP) is. We show here that sneutrino can naturally be the NLSP in the Non-Universal Higgs Masses (NUHM) model, and that this scenario is still phenomenologically viable.
