Since the discovery three years ago (by James Christenson, James Cronin, Val Fitch and Rene Turlay) that the product of the charge conjugation operator (C) and the parity operator (P) is not conserved in the weak interaction, particle physicists have been trying to find out how and why this occurs. The latest experiments on the decay of the K2° meson, reported in Phys. Rev. Letters, 23 Oct., seem to show a charge asymmetry in the leptonic decay of K2°.
