Abstract

AbstractWe present measurements of the branching fractions of eight

$$ {\overline{B}}^0 $$

B ¯ 0 → D(*)+K−

$$ {K}_{(S)}^{\left(\ast \right)0} $$

K S ∗ 0 , B− → D(*)0K−

$$ {K}_{(S)}^{\left(\ast \right)0} $$

K S ∗ 0 decay channels. The results are based on data from SuperKEKB electron-positron collisions at the Υ(4S) resonance collected with the Belle II detector, corresponding to an integrated luminosity of 362 fb−1. The event yields are extracted from fits to the distributions of the difference between expected and observed B meson energy, and are efficiency-corrected as a function of m(K−

$$ {K}_{(S)}^{\left(\ast \right)0} $$

K S ∗ 0 ) and m(D(*)

$$ {K}_{(S)}^{\left(\ast \right)0} $$

K S ∗ 0 ) in order to avoid dependence on the decay model. These results include the first observation of

$$ {\overline{B}}^0 $$

B ¯ 0 → D+K−

$$ {K}_S^0 $$

K S 0 , B− → D*0K−

$$ {K}_S^0 $$

K S 0 , and

$$ {\overline{B}}^0 $$

B ¯ 0 → D*+K−

$$ {K}_S^0 $$

K S 0 decays and a significant improvement in the precision of the other channels compared to previous measurements. The helicity-angle distributions and the invariant mass distributions of the K−

$$ {K}_{(S)}^{\left(\ast \right)0} $$

K S ∗ 0 systems are compatible with quasi-two-body decays via a resonant transition with spin-parity JP = 1− for the K−

$$ {K}_S^0 $$

K S 0 systems and JP = 1+ for the K−K*0 systems. We also present measurements of the branching fractions of four

$$ {\overline{B}}^0 $$

B ¯ 0 → D(*)+

$$ {D}_s^{-} $$

D s − , B− → D(*)0

$$ {D}_s^{-} $$

D s − decay channels with a precision compatible to the current world averages.
