WebMay 23, 2024 · The complete question includes particles like p, e −, Λ and Ω. It's pretty easy to understand why Ω and Λ have to decay weakly; Ω has three s quarks so, no other baryon to turn into without changing strangeness. As for Λ, it is the lightest baryon with unit strangeness. But when it comes to, for example, Σ 0 it can decay to Λ + γ.
