Stable massive particles (SMPs) are hypothetical particles that are long-lived and have appreciable mass. The precise definition varies depending on the different experimental or observational searches. SMPs may be defined as being at least as massive as electrons, and not decaying during its passage through a detector. They can be neutral or charged or carry a fractional charge, and interact with matter through gravitational force, strong force, weak force, electromagnetic force or any unknown force.
If new SMPs are ever discovered, several questions related to the origin and constituent of dark matter, and about the unification of four fundamental forces may be answered.[example needed]
