Abstract

Using data from the E791 fixed-target hadroproduction experiment at Fermilab, we have studied the Cabibbo-favored but phase-space-suppressed decay D⁰→K^-K^-K⁺π⁺. We find the decay rate for this mode to be (0.54±0.16±0.08) × 10^-2 times that for the normalization mode D⁰→K^-π^-π⁺π ⁺. We observe a clear signal for D⁰→φK^-π⁺ which is consistent with producing 0.7±0.3 of the D⁰→K^-K^-K⁺π⁺ signal. In the context of simple models, we use our measurements to estimate the importance of decay amplitudes that produce extra quark-antiquark pairs from the vacuum relative to those that do not.
