    Decay Weak
Click For Summary
Strong decay processes, such as the decay of ∑0(1385) to Λ + π0, occur in extremely short timescales of about 10^-23 seconds and are mediated by gluons. In contrast, weak decay processes have longer lifetimes, around 10^-10 seconds, due to the inherently weaker nature of the weak interaction. This difference in decay times is attributed to the strength of the forces involved, with weaker forces leading to slower evolution of the system. The weak force corresponds to lower energy processes, resulting in a slower decay rate. Understanding these distinctions is crucial for comprehending particle interactions and lifetimes in physics.

I read in my textbook that a decay process involving the strong interaction has a very short lifetime (10^-23s) whereas a decay process involving the weak interaction has a longer lifetime (10^-10s). Why is this?
 
Physics news on Phys.org
That's because the weak interaction is weaker (hence the name)
 
If you check a source like wikipedia on the strong and weak force, you'll find they atre involved in quite different action phenomena...

What is a 'decay process' involving the strong force?

For example, "www.oeaw.ac.at/smi/uploads/media/ETP-WS09-Lesson11.pdf‎" mentions ∑0(1385) → Λ + π0 as a strong decay, taking place in 10-23 sec and mediated by a gluon.

Qualitatively, you may think that the weak force is weaker, so the system evolves more slowly, thus takes longer time to decay.
Or, in other words, weaker force corresponds to lower energy process, i.e. the time evolution ##e^{-iEt}## is slow .
