For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic particles. Symmetry in physics basically means that some rules of nature ...
The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...
With the discovery of the charm quark in 1974, there opened a new era of studying the heavy quark in the particle physics. Up to now, the Standard Model (SM) has been widely recognized as the theory ...
