The charm quark is a heavier cousin of the up and down quarks that make up much of the matter around us.
Whereas matter on Earth and in stars is made of atoms and nuclei, scientists know that dark matter must be made of something else. Neutralinos are a prime candidate.
Particle accelerators are used for a variety of purposes worldwide.
A quench occurs when a magnet in a particle accelerator loses its superconductivity.
Neutrino masses are extremely difficult to measure. While we know precisely how much an electron weighs, we have little information on the mass of its neutral partner, the electron neutrino. The same is true of the muon neutrino and tau neutrino.
The Z boson is a neutral particle that mediates the weak force.
Scientists search for rare decays to test their understanding of how matter behaves.
The W boson is a charged force-carrying particle that transmits the weak force.
The Terascale is an energy region named for the tera, or million million, electronvolts of energy needed to access it. Physicists are standing at its threshold, poised to enter this uncharted territory of the subatomic world.
A jet forms when a quark or gluon is produced in a high-energy particle collision.
