The authors report on a search for the decay B^± → D$$(*)±\atop{s}$$Φ using 212.2 fb^-1 of data collected with the BABAR detector at the PEP-II B Factory at the Stanford Linear Accelerator Center between 1999 and 2004. This sample of 234 x 10⁶ e⁺e^- → Y(4S) → B$$\bar{B}$$ events yields no significant signal. They report the Bayesian upper limits β(B^± → D$$(*)±\atop{s}$$Φ) x β(D$$(*)±\atop{s}$$ → Φπ^±) < 8.6 x 10^-8 and β(B^± → D$$(*)±\atop{s}$$^±Φ) x β(D_s^± → Φπ^±) < 5.4 x 10^-7 at the 90% C.L. Using the latest measurement of β(D$$(*)±\atop{s}$$ → Φπ^±), they report: β(B^± → D_s^±Φ) < 1.8 x 10^-6 and β(B^± → D*_s^±Φ) < 1.1 x 10^-5 at the 90% C.L.
