Abstract: (APS)

If the branching ratio for D0→K−π+π0, which currently stands at (12±6)%, remains much larger than 3% in future data, then either the ΔT=1 rule breaks down, or the final-state K¯ππ contains much structure. The possibility that this structure is due to K¯* and ρ resonances is briefly examined.
