Description
We report on searches for B- → DS-φ and B- → D*S-φ. In the context of the Standard Model the branching fractions for these decays are expected to be highly suppressed, since they proceed through annihilation of the b and (bar u) quarks in the B- meson. Our results are based on 234 million Υ(42) → B(bar B) decays collected with the BABAR detector at SLAC. We find no evidence for these decays, and we set 90% confidence level upper limits on the branching fractions Β(B- → DS-φ) < 1.8 x 10-6; Β(B- → D*S-φ) < 1.1 x 10-5. These results are consistent with Standard Model expectations
