W and Z bosons have masses around 80 GeV/c²
The Higgs mechanism explains how W and Z bosons acquire mass despite the Standard Model initially predicting them to be massless. This mechanism involves the Higgs field, which permeates all space and causes spontaneous symmetry breaking at extremely high temperatures. The breaking of symmetry triggers the Higgs mechanism, giving mass to the W± and Z bosons.
Example
The Large Hadron Collider at CERN confirmed the existence of the Higgs particle on March 14, 2013, supporting the Higgs mechanism's role in generating mass for W and Z bosons.
Understanding the Higgs mechanism is crucial for explaining why W and Z bosons have mass, which is essential for the Standard Model of particle physics.
