yläosahiukkasia
Yläosahiukkasia, known in English as "top quarks," are fundamental particles in particle physics. They are members of the third generation of quarks, which are the building blocks of hadrons like protons and neutrons. Top quarks are distinguished by their exceptionally large mass, making them the heaviest known fundamental particle. Their mass is comparable to that of a gold atom, despite being a fundamental fermion.
Due to their significant mass, top quarks are highly unstable. They decay very rapidly, with a lifetime
The discovery of the top quark was a major achievement in particle physics, confirmed at the Fermi
