A gauge boson with no electric charge. It mediates the weak neutral current. It was studied in spectacular detailed by experiments at LEP and the SLC.

An experiment located at the DESY laboratory. ZEUS uses the electron-proton collider called HERA. For more information, see: http://www-zeus.desy.de/.

A very weak interaction that is independent of the electric charge of a particle. Particles can exchange energy through this mechanism, but other characteristics of the particles remain unchanged. This force is mediated by the Z-boson.

(Weakly Interacting Massive Particle): These as yet undiscovered particles are a leading candidate for dark matter.

This underground cavern, located in Carlsbad, New Mexico, is a storage site for nuclear waste. It is also a proposed location for a National Underground Sciences Laboratory.

A proposed Cherenkov detector experiment to search for proton decay, and neutrino oscillations.

A veto detector is used for eliminating possible false signals in an experiment. When a false signal has a notable feature, a veto detector can be built to look for that feature. In this way, when the veto detector registers a signal, the data associated with that signal can be flagged, and removed from the subsequent analysis.

A 2 TeV proton on anti-proton collider that operates at Fermilab in Batavia, Illinois. The top quark was discovered using this accelerator.

The strength of an interaction involving three particles. In the case where all three particles are identical, it is known as the trilinear self-coupling.
