624 Particle Physics and CosmologySection 46.4Classification of ParticlesP46.10In ? +→+++pnµ, charge conservation requires the unknown particle to be neutral. Baryonnumber conservation requires baryon number = 0. The muon-lepton number of ? must be –1.So the unknown particle must be ν.P46.11ΩΛ→+0KKS0+−ππ(or 00+)Λ0+pπnpee→+ ++Section 46.5Conservation LawsP46.12(a)ppe+→ +Le00 01+→+andL10−+(b)charge−+→++11(c)p pp+baryon number :1 11 0(d)pp ppn+→++baryon number :11 111(e)γπ0charge01 00P46.13(a)Baryon number and charge are conserved, with values of0 1 0 1+=+and1 1 1 1in both reactions.(b)Strangeness is
