Search for the Decay of D+ and D_s+ Mesons to Three Charged Kaons
by P.L. Frabetti et al.
We report the results of a search for the doubly Cabibbo suppressed decays
D+ --> K+ K- K+ and D+ --> phi K+, and the singly Cabibbo suppressed decays
D_s+ --> K+ K- K+ and D_s+ --> phi K+. Our measurements are all consistent
with zero branching ratio, and we set upper limits on the relative D+
B(phi K+) / B(phi pi+) < 0.021,
B(K+ K- K+) / B(phi pi+) < 0.025,
B(K+ K- K+) / B(K- pi+ pi+) < 0.0016,
and the relative D_s+ branching ratios:
B(phi K+) / B(phi pi+) < 0.013,
B(K+ K- K+) / B(phi pi+) < 0.016.
The data were accumulated by the Fermilab high energy photoproduction
