Rediscovery of $D^0\to\K^0_S\pi^+\pi^-$ decays in early Belle II dataPublic
This note presents plots for rediscovery of the $D^{*+}\to D^0\pi^+$, $D^0\to\K^0_S\pi^+\pi^-$ decays, using the data collected by Belle II during 2019, which correspond to 9.6\fb^{-1} of integrated luminosity. The fit to $M(D^0)$ vs $Q$ 2D distribution, fit to $D^0$ decay-time and Dalitz distributions are shown in this note. |

Dark Matter searches at Belle IIPublic
The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is $8\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than its predecessor. Durin… |

Trigger efficiencies for single photon eventsPublic
The search for invisible decays of the dark photon A′ is enabled by dedicated single photon triggers. A radiative muon pair control sample has been used to measure the efficiency of the level 1 and high-level triggers as a function of energy. This document contains the approved plots and captions. |

Measurement of Hadronic Mass Moments in B->Xclv Decays at Belle IIPublic
We present a measurement of the first six hadronic mass moments in semi-leptonic $B\rightarrow X_c \ell \nu$ decays. The measurement is using the Belle~II data-set recorded at the $\Upsilon(4\mathrm{S}$ resonance in 2019 and 2020 (March-July), corresponding to an integrated luminosity of \SI{34.58}{fb^{-1}}. The decay $\Upsilon(4\mathrm{S})\righta… |

Performance of Belle II tracking on collision dataPublic
The tracking system of Belle II consists of a silicon vertex detector (VXD) and a cylindrical drift chamber (CDC), both operating in a magnetic field created by the main solenoid of 1.5 T and final focusing magnets. The tracking algorithms employed at Belle II are based on a standalone reconstruction in SVD and CDC as well as on a combination of t… |
