Quarks Quarks- any group of subatomic particles believed to be among the basic components if matter Quarks are believed to be the fundamental constituents of matter, and have no apparent structure. They are the particles that make up protons and neutrons, which make up the nucleus of atoms. Also, particles that interact by means of the strong force, the force that holds parts of the nucleus together, are explained in terms of quarks. Other baryons …showed first 75 words of 585 total…

…showed last 75 words of 585 total…quarks results in conversion of energy to new quarks and antiquarks with which the first quark combines(1985 Quarks). After the discovery of "bottom" and "charm" it was believed that all quarks occur in pairs. This led to the effort to find "top" quark. In 1984 the laboratory of the European Council for Nuclear Research (CERN) in Geneva obtained experimental evidence of "top's" existence. The discovery of "top" completes the theory of natures basic components, quarks(1985 Quarks).
