Weinberg angle
The Weinberg angle, also known as the weak mixing angle, is a fundamental parameter in particle physics that describes how much the weak nuclear force and electromagnetism mix with each other. It helps explain the behavior of particles, particularly in the context of the electroweak theory, which unifies these forces at high energies. A key aspect is that it determines the strengths of the interactions between different particles, influencing phenomena like particle decay and interactions in the universe. Understanding this angle improves our grasp of the fundamental forces shaping the cosmos.
