What factors influence the decay width of particles?

Click For Summary
The decay width of particles is influenced primarily by their momentum and spin. These physical quantities play a significant role in determining how quickly a particle decays. The relationship between decay width and these factors is essential for understanding particle behavior in quantum physics. Additionally, the discussion suggests that there may be general dependencies applicable across various particle types. Understanding these influences is crucial for advancements in particle physics research.
