The Belle II Experiment: Status and ProspectsPublic
The Belle II experiment is a substantial upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric e+e− collider. The accelerator has already successfully completed the first phase of commissioning in 2016. First electron positron collisions in Belle II are expected for April 2018. The design luminosity of SuperKEKB is 8×10… |

Plots for the φ meson produced in e+e− → φγ events in 250 pb^{-1} collision dataPublic
We reconstruct the φ meson produced in the ISR process e+e− → φγ in its decay to two charged kaons φ → K+K− using about 250 pb−1 of early collision data of Belle II phase 2 operation. |

Prospects of conventional and exotic bottomonium physics at BELLE IIPublic
Belle II is a next generation B-factory experiment at the SuperKEKB collider. In early 2019 the fully operational detector will start taking data. The goal is to collect an integrated luminosity of 50 ab-1, a statistics 50 times larger than the one collected by its predecessor Belle. Belle II offers the most promising prospects for bottomonium phy… |

Public analysis of Belle II DataPublic
A small Belle II data sample will be available to the general public through an interactive graphical application which includes basic particle selection tools for reconstructed particles. The application is using an open source library Blockly running in an HTML5 capable browser. In the application, different particle decays can be described by s… |

Missing Energy B Decays at the Belle II ExperimentPublic
The Belle II experiment at the SuperKEKB collider is a major upgrade of the KEK "B factory" facility in Tsukuba, Japan. The machine is designed for an instantaneous luminosity of 8 $\times 10^{35}\mathrm{cm^{-2}s^{-1}}$, and the experiment is expected to accumulate a data sample of about 50 $\mathrm{ab^{-1}}$. With this amount of data, decays se… |
