1198. Reconstruction of B0 -> J/ψKS0 and B+ -> J/ψK+ / Y. Yusa [BELLE2-NOTE-PL-2020-004]
21 April 2020

In this public note, we describe the reconstruction of the CP eigenstate of B0-> J/\psi K0S and its control sample of B+ -> J/\psi K+ using the data set taken from the 2019 runs recorded by the Belle II which corresponds to an integrated luminosity of 8.7 /fb..

1199. Measurement of the branching fraction of $B^{0}\to D^{*-}l^{+}\nu_{l}$ with early Belle II data / Minakshi Nayak ; Abner Soffer ; Florian Bernlochner ; Lu Cao ; et al [BELLE2-CONF-PH-2020-002]
15 April 2020

We measure the branching fractions for the decays $B^{0}\to D^{*-}e^{+}\nu_{e}$ and $B^{*0}\to D^{*-}\mu^{+}\nu_{\mu}$ using the first $8.70 \pm 0.09 fb^{-}$ of data collected by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+ e^-$ collider using the decays $D^{*+}\to D^0 \pi^+$ and $D^0\to K^-\pi^+$..
