Abstract

Using data from the E791 fixed-target hadroproduction experiment at Fermilab, we have studied the Cabibbo-favored but phase-space-suppressed decay D-0-->K- K- K+ pi (+). We find the decay rate for this mode to be (0.54+/-0.16+/-0.08) x 10(-2) times that for the normalization mode D-0-->K- pi (-) pi(+) pi (+). We observe a clear signal for D-0-->phiK(-) pi (+) which is consistent with producing 0.7+/-0.3 of the D-0-K- K- K+ pi (+) signal. In thecontext 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.
