Strange New Particle?

At the smallest scales, everything in the universe can be broken down into fundamental morsels called particles. The Standard Model of particle physics—the reigning theory of these morsels—describes a small collection of known species that combine in myriad ways to build the matter around us and carry the forces of nature. Yet physicists know that these particles cannot be all there is—they do not account for the dark matter or dark energy that seem to contribute much of the universe’s mass, for example. Now two experiments have observed particles misbehaving in ways not predicted by any known laws of physics, potentially suggesting the existence of some new type of particle beyond the standard zoo.
