Abstract
Considering scenarios in which the gravitino is the lightest supersymmetric particle and a charged slepton the next-to-lightest supersymmetric particle (NLSP), we discuss cosmological constraints on the masses of the gravitino and the NLSP slepton. The presented mass bounds are crucial for gravitino dark matter studies and potential gravitino signatures at future colliders.
