Top quark

The top quark is a fundamental particle, one of the building blocks of matter, discovered in 1995. It’s the heaviest known elementary particle, much heavier than most other particles, which influences how it behaves and interacts. The top quark plays a key role in the Standard Model of physics, helping scientists understand the fundamental forces of nature. It exists briefly in particle collisions before decaying into lighter particles. Its unique properties make it essential for exploring fundamental physics questions and testing our understanding of the universe at its smallest scales.
