Reactions involving elementary particles conserve, among other quantities, baryon number, lepton number, strangeness, and charge. Identify the violated conservation law making each of the following reactions impossible, (a) K⁺ → π⁺ + π⁰ (b) n → p + e⁻ (c) p → e⁺ + v_e (d) A° → p + π⁻

Analyze the following decays in terms of the quark content ofthe particles

a.) Ω- to ^⁰+K-

b.)n to p=e-+v_e

c.)π⁰ to γ+γ

d.)K⁰ to π⁺ +π^-

e.) Δ*⁺⁺ to p + π^-

f.) Σ- to n+π^-
