We present final results of a sensitive search for new particles in π ^± K^∓ effective mass spectra observed in proton-nucleus collisions at 400 GeV/ c . We establish a limit for D⁰ (1.865) production B_π⁺π^-dσ/dy < 360 nb/nucleon at y_cm^≈ -0.4. For $$\bar{D}$$₀ → π^-K⁺ the limit is 290 nb/nucleon.
