D) weak nuclear force

Question

Quizplus · Accepted Answer

The symmetry breaking that led to the existence of matter over antimatter in the universe is most closely associated with the weak nuclear force. This force is responsible for processes such as beta decay and plays a key role in the Standard Model of particle physics, particularly in explaining the observed asymmetry between matter and antimatter.
