Abstract:	First observations of the B(s)(0) -> D(s)(-) pi(+), B(s)(0) -> D(s)()(-)s rho(+) and B(s)(0) -> D(s)(-) rho(+) decays are reported together with measurements of their branching fractions. B(B(s)(0) -> D(s)(-) pi(+)) = [2.4(-0.4)(+0.5)(stat) +/- 0.3(syst) +/- (0.4(f(s))] x 10(-3), B(B(s)(0) -> D(s)(-) rho(+)) = [8.50(-1.2)(+1.3)(stat) +/- 1.1(syst) +/- 1.3(f(s))] x 10(-3) and B(s)(0) -> D(s)()(-)s rho(+) = [11.9(-2.0)(+2.2)(stat) +/- 1.7(syst) +/- 1.8(f(s)) x 10(-3) (f(s) = N(Bs()1) ((B) over bars()) / N b (b) over bar). From helicity- angle distributions, we measured the longitudinal polarization fraction in B(s)(0) -> D(s)()(-)s rho(+) decays to be f(L)(B(s)(0) -> D(s)()(-)s rho(+)) = 1.05(-0.10)(+0.08)(stat)(-0.04)(+0.03)(syst). These results are based on a 23.6 fb(-1) data sample collected at the Y(5S) resonance with the Belle detector at the KEKB e(+)e(-) collider.
