Abstract
We report the results of a search for the doubly Cabibbo suppressed de cays 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 90% confidence le vel upper limits on the relative D+ branching ratios: BR(phi K+)/BR(ph i pi(+)) < 0.021, BR(K+K-K+)/BR(phi pi(+)) < 0.025 and BR(K+K-K+)/BR(K (-)pi(+)pi(+)) < 0.0016, and the relative D-s(+) branching ratios: BR( phi K+)/BR(phi pi(+)) < 0.013 and BR(K+K-K+)/BR(phi pi(+)) < 0.016. Th e data were accumulated by the Fermilab high energy photoproduction ex periment E687.
