Particle Conservation Laws

Which of the following decays cannot occur because the law of conservation of lepton number is violated?

(a) \(n \rightarrow p+e^{-}\)

(b) \(\mu^{+} \rightarrow \mathrm{e}^{+}+v_{\mathrm{e}}\)

(c) \(\pi^{+} \rightarrow \mathrm{e}^{+}+v_{\mathrm{e}}+\bar{v}_{\mu}\)

(d) \(\mathrm{p} \rightarrow \mathrm{n}+\mathrm{e}^{+}+v_{\mathrm{e}}\)

(e) \(\pi^{-} \rightarrow \mathrm{e}^{-}+\bar{v}_{\mathrm{e}}\)

(f) \(\mu^{-} \rightarrow \mathrm{e}^{-}+\bar{v}_{\mathrm{e}}+v_{\mu}\)

(g) \(\Lambda^{0} \rightarrow \pi^{-}+p\)

(h) \(\mathrm{K}^{+} \rightarrow \mu^{+}+v_{\mu}\)

n rightarrow p + e^-

mu^+ rightarrow e^+ + v_e

pi^+ rightarrow e^+ + v_e + bar v_mu

p rightarrow n + e^+ + v_e

pi^-1 rightarrow e^- + bar v_e

mu^- rightarrow e^- + bar v_e + v_mu

Lambda^0 rightarrow pi^- + p

K^+ rightarrow mu^+ + v_mu
