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

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.
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.
