A proton accelerator at Fermilab which can accelerate protons tonearly one trillion electron volts (1 TeV). Two detectors, CDF and D0,detect the results when these protons collide. Recently these detectors havedetected the heaviest-known quark, the top.

The Deutsches Elektronen-Synchrotron (DESY) in Hamburg.The HERA accelerator is located at DESY.

HERA is an electron-protoncollider at DESY, which uses theelectrons as a probe to understand the structure of the proton.The results of these collisions are detected by two detectors, ZEUSand H1.

The Fermi National AcceleratorLaboratory which is situated 30 miles west of Chicago.The Tevatron accelerator is located at Fermilab.

The Large Electron Positron collider, the world's largest particleaccelerator, which is 26.7 km in circumference and some 100 metres underground,situated at CERN. LEP collides electrons and positrons atenergies sufficent to produce the Z and (soon) W particles, carriers of theweak force.

In almost all circumstances antimatter seen in a mirror behaveslike normal matter. Very occasionally, in the decay of kaons (andperhaps in the decay of B-mesons, though this has not yet been seen), thisrule is violated. This is known as CP violation.Experimental Particle Physics

Particle Physics is the study of thebasic elements of matter and the forces acting among them. It aims to determinethe fundamental laws that control the make up of matter and the physicaluniverse.

The theory that all hadrons, such as the protons andneutrons in the nucleus, are made ofquarks.

One electron Volt (eV)is the energy gained by an electron when it is accelerated through apotential of 1 Volt.The binding energy on an electron in an atom is of the order of 1 eV.

Property of quarks associated with their binding with gluons.
