Weinberg-Salam model

The Weinberg–Salam model is a fundamental theory in physics that describes how particles acquire mass and interact through the weak nuclear force, one of the four fundamental forces. It combines electromagnetic and weak forces into a single framework called electroweak theory. This model predicts the existence of the W and Z bosons, the particles responsible for weak interactions, and explains how particles like electrons and quarks get their mass through a process called spontaneous symmetry breaking involving the Higgs field. It is a key part of the Standard Model of particle physics, unifying our understanding of subatomic particles and forces.
