First Simultaneous Determination of Inclusive and Exclusive |Vub|

L. Cao, F. U. Bernlochner, K. Tackmann, I. Adachi et autres

The first simultaneous determination of the absolute value of the Cabibbo-Kobayashi-Maskawa matrix element ${V}_{ub}$ using inclusive and exclusive decays is performed with the full Belle data set at the $\mathrm{\ensuremath{\Upsilon}}(4S)$ resonance, corresponding to an integrated luminosity of $711\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. We analyze …

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

Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed et autres

We report a measurement of the mixing-induced and direct $\textit{CP}$ violation parameters $S_{\text{CP}}$ and $A_{\text{CP}}$ from $B^0 \to J/ψK^0_S$ decays reconstructed by the Belle II experiment at the SuperKEKB asymmetric-energy electron-positron collider. The data, collected at the center-of-mass energy of the $Υ(4S)$ …

Novel method for the identification of the production flavor of neutral charmed mesons

I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara et autres

We propose a new algorithm for the identification of the production flavor of neutral $D$ mesons in the Belle II experiment. The algorithm exploits the correlation between the flavor of a reconstructed neutral $D$ meson (signal $D$ meson) and the electric charges …
