We report the results of a search for the doubly Cabibbo suppressed decays D+ → K+K-K+ and D+ → ΦK+, and the singly Cabibbo suppressed decays Ds+ → K+K-K+ and Ds+ → ΦK+. Our measurements are all consistent with zero branching ratio, and we set 90% confidence level upper limits on the relative D+ branching ratios: BR(ΦK+) BR(Φπ+) < 0.021, BR(K+K-K+) BR(Φπ+) < 0.025 and BR(K+K-K+) BR(K-π+π+) < 0.0016, and the relative Ds+ branching ratios: BR(ΦK+) BR(Φπ+) < 0.013 and BR(K+K-K+) BR(Φπ+) < 0.016. The data were accumulated by the Fermilab high energy photoproduction experiment E687.

Abstract

We report the results of a search for the doubly Cabibbo suppressed decays D+ → K+K-K+ and D+ → ΦK+, and the singly Cabibbo suppressed decays Ds+ → K+K-K+ and Ds+ → ΦK+. Our measurements are all consistent with zero branching ratio, and we set 90% confidence level upper limits on the relative D+ branching ratios: BR(ΦK+) BR(Φπ+) < 0.021, BR(K+K-K+) BR(Φπ+) < 0.025 and BR(K+K-K+) BR(K-π+π+) < 0.0016, and the relative Ds+ branching ratios: BR(ΦK+) BR(Φπ+) < 0.013 and BR(K+K-K+) BR(Φπ+) < 0.016. The data were accumulated by the Fermilab high energy photoproduction experiment E687.
