Why Do Particles Decay
Why Do Particles Decay . Most particles decay — yet some don’t! Because of the charge conservation, electrons cannot become lighter particles with no electric charges, which is why more massive charged particles like muons ( μ ), taus ( τ) or mesons ( π) eventually decay into electrons ( e ). Beta Decay from www.sliderbase.com So, if the decay products have lower energy than the initial particle, the decay can happen spontaneously. One example is when a uranium nucleus breaks into thorium and helium nuclei. And why do particles decay in the first place?
