Unformatted text preview: 16. (a) Referring to Tables 45-3 and 45-4, we find the strangeness of K0 is +1, while it is zero for both π + and π − . Consequently, strangeness is not conserved in this decay; K0 → π + + π − does not proceed via the strong interaction. (b) The strangeness of each side is −1, which implies that the decay is governed by the strong interaction. (c) The strangeness or Λ0 is −1 while that of p+π − is zero, so the decay is not via the strong interaction. (d) The strangeness of each side is −1; it proceeds via the strong interaction. ...
