weakly interacting massive particle

weakly interacting massive particle (plural weakly interacting massive particles)

1. (astronomy, physics) A hypothetical class of particle, proposed to explain the dark matter problem.

There are two definitions for WIMPs, one where "weakly interacting" signifies weak nuclear force, a fundamental force of nature, and the other where "weakly interacting" signifies low strength interaction with normal matter such as only interacting through gravitational force.
