  The top quark, the heaviest elementary particle known to date, was discovered by the CDF and D0 collaborations in 1995. In more than 25 years since the discovery the properties of the top quark have been studied in detail.



The top quark is one of six known quarks in the Standard Model theory. It is an 'up-type' quark, and is believed to have the same properties as the up (u) and charm (c) quarks, except for its mass.

The Standard Model of particle physics describes the interactions between the elementary building blocks of matter: quarks and leptons.
