Fredagskollokvium: Are Raklev: Gravitino - the black sheep sparticle

In this talk I want to review some of the phenomenological properties of the gravitino, the hypothetical supersymmetric partner of the hypothetical graviton. Gravitinos have long been considered a nuisance in supersymmetric theories, but work over the last five years have revealed some interesting properties which could make the gravitino an excellent candidate for dark matter. I will also try to cover what attempts at finding gravitinos are currently being made, and what we hope to learn from them.
