Measurement of decay-time-dependent $\textit{CP}$ violation in $B^0 \to J/\psi K^0_S$ decays using 2019-2021 Belle II data

B. C. I. Adachi, +391 more
TL;DR: In this article , the mixing-induced and direct violation parameters of the Belle II experiment at the SuperKEKB asymmetric-energy electron-positron collider were measured at the center-of-mass energy of the 4S resonance.

Angular analysis of the low $K^{+}K^{-}$ invariant mass enhancement in $B^{+}\to K^{+}K^{-}\pi^{+}$ decays

Belle Collaboration C.-L. Hsu, +201 more
TL;DR: In this article , a coherent sum model for the angular distribution of S$- and P$-wave pairs with invariant mass below 1.1$ GeV/$c^2 was proposed.

Measurement of the $B^+/B^0$ production ratio in $e^+e^-$ collisions at the $\Upsilon(4S)$ resonance using $B \rightarrow J/\psi(\ell\ell) K$ decays at Belle

B. S. Choudhury, +196 more
TL;DR: In this article , the authors measured the decay rate ratio of branching fractions for the 4S resonance with the Belle detector and found that the decay ratio was 1.065/pm 0.047, which is the most precise measurement to date.

Measurements of the branching fractions $\mathcal{B} (\bar{B}{}^0 \to D^{*+} \pi^-)$ and $\mathcal{B} (\bar{B}{}^0 \to D^{*+} K^-)$ and tests of QCD factorization

Belle Collaboration J. F. Krohn, +197 more
TL;DR: In this paper , the authors reported the branching fractions B (B 0 → D ∗ + π − ) = (2 . 62 ± 0. 02 ± 0 . 09) × 10 − 3 and B 0 →D ∗+ K − ) was found to be consistent with unity and therefore no evidence for SU (3) symmetry breaking was found at the 5% precision level.

J. F. Krohn, +197 more
TL;DR: In this article , the authors reported the branching fractions B(B¯0→D*+π−)=(2.62±0.13)×10−2, where systematic uncertainties due to the D*+ meson reconstruction cancel out.
