Coleman-Weinberg Mechanism

The Coleman-Weinberg mechanism is a theoretical framework in particle physics that explains how particles can gain mass through a process involving the interactions of quantum fields. It suggests that when certain conditions are met, an originally massless particle, like the Higgs boson, can acquire mass due to its interactions with a fluctuating quantum field. This mechanism helps to explain the mass of elementary particles in the universe and is significant for understanding how fundamental forces operate, particularly in the context of the early universe and the development of the Standard Model of particle physics.
