The Standard Model is a fundamental theory in physics that describes the basic building blocks of matter and the forces that govern their interactions. It includes elementary particles such as quarks, leptons, and bosons, which are the constituents of atoms and the carriers of forces. This model successfully explains three of the four known fundamental forces: the electromagnetic force, the weak nuclear force, and the strong nuclear force. However, it does not incorporate gravity, which is described by general relativity. The Standard Model has been confirmed through numerous experiments, including those conducted at the Large Hadron Collider.
