Noun1.weakly interacting massive particle - a hypothetical subatomic particle of large mass that interacts weakly with ordinary matter through gravitation; postulated as a constituent of the dark matter of the universe
natural philosophy, physics - the science of matter and energy and their interactions; "his favorite subject was physics"
acronym - a word formed from the initial letters of the several words in the name
elementary particle, fundamental particle - (physics) a particle that is less complex than an atom; regarded as constituents of all matter
dark matter - (cosmology) a hypothetical form of matter that is believed to make up 90 percent of the universe; it is invisible (does not absorb or emit light) and does not collide with atomic particles but exerts gravitational force

A massive superpartner should have precisely the properties needed to account for the dark matter in space; it would interact only weakly with ordinary matter, inspiring the nickname of WIMP (weakly interacting massive particle).
Washington, April 16 ( ANI ): An international team of researchers has for the first time observed a concrete hint of what physicists believe to be the particle behind dark matter and therefore nearly a quarter of the universe-a WIMP, or weakly interacting massive particle.
"We now have a compelling hypothesis, namely that dark matter is comprised of WIMPs (Weakly Interacting Massive Particle), particles that don't radiate light and interact rarely with ordinary matter.
There are currently two hypothetical dark matter particle candidates - the Weakly Interacting Massive Particle (WIMP), which, as their name suggests, are heavy particles that interact with normal matter only through gravity and the weak nuclear force, and axions, which are much lighter.
The CoGeNT experiment looks for a type of dark-matter particle called a WIMP, or Weakly Interacting Massive Particle.
The leading candidate for a dark matter particle is the vaguely named "weakly interacting massive particle," or WIMP.
They believe that it consists of a proposed particle left over from the Big Bang called the WIMP, for weakly interacting massive particle. WIMPs sense only gravity and the weak force, the interaction that governs radioactive decay.
Either ordinary cosmic ray particles are reacting with the nuclei in an unknown way or some exotic form of matter, perhaps a weakly interacting massive particle (WIMP), is causing the destruction (SN: 2/26/00, p.
The current detectors which are looking for Weakly Interacting Massive Particles, a widely discussed form of dark matter, won't benefit from this prediction, but by assimilating the prediction, O'Hare says that they expect to establish a baseline for what should appear in a dark matter experiment.
The greatest focus has been on weakly interacting massive particles (WIMPs), beefy hypothetical entities that interact with matter only weakly.
Some theories about the composition of dark matter suggest that it consists of Weakly Interacting Massive Particles (WIMPs) that release high-frequency gamma rays when they annihilate each other.
