Abstract
Using 3.1fb(-1) of data accumulated at the Υ(4S) by the CLEO-II detector, corresponding to 3.3×10(6) BB¯ pairs, we have searched for the color-suppressed B hadronic decay processes B(0)→D(0)(D*(0))X(0), where X(0) is a light neutral meson π(0), ρ(0(, η, η′ or ω. The D*(0) mesons are reconstructed in D*(0)→D(0)π(0) and the D(0) mesons in D(0)→K(-)π(+), K(-)π(+)π(0) and K(-)π(+)π(+)π(-) decay modes. No obvious signal is observed. We set 90% C.L. upper limits on these modes, varying from 1.2×10(-4) for B(0)→D(0)π(0) to 1.9×10(-3) for B(0)→D*(0)η′.
