14. To examine the conservation laws associated with the proposed reaction 0 pp e +− +→ Λ+ Σ+ , we make use of particle properties found in Tables 44-3 and 44-4. (a) With (p) 1, (p) 1, qq =+ =− 0 ()0 , q Λ = () 1 q + Σ and ( ) 1 qe , we have 1(1 ) 01(1 ) +− = ++− . Thus, the process conserves charge. (b) With 1, (p) BB 0 ()1 , B Λ = B + Σ and ( ) 0 Be = , we have )110 +− ≠ ++ . Thus, the process does not conserve baryon number. (c) With 0, ee LL == 0 () ()0 + Λ= Σ= and ( ) 1 e Le = , we have 00001 +≠++ , so the process does not conserve electron lepton number. (d) All the particles on either side of the reaction equation are fermions with
