Computing at Belle IIPublic
The existence of large matter-antimatter asymmetry (CP violation) in the b-quark system as predicted in the Kobayashi-Maskawa theory was established by the B-Factory experiments, Belle and BaBar. However, this cannot explain the magnitude of the matter-antimatter asymmetry of the universe we live in today. This indicates undiscovered new physics e… |

Report on Distributed Computing and Data Handling at Belle II ExperimentPublic
We introduce the distributed computing and data handling systems at Belle II, a next-generation B factory experiment at KEK. The systems have to handle an amount of data eventually corresponding to 50 times the level of its predecessor experiment, Belle, by the end of 2022. The data size is comparable to or more than the ones of LHC experiments. F… |

The Belle II Physics Analysis Model Public
The Belle II experiment is a future flavour factory experiment at the intensity frontier SuperKEKB e+e- collider, KEK Japan. Belle II is expected to go online in 2015, and collect a total of 50 ab-1 of data by 2022. The data will be used to study rare flavour phenomena in the decays of B- and D- mesons and tau-leptons, as well as heavy meson spect… |

Track extrapolation and muon identification using GEANT4E in event reconstruction in the Belle II experimentPublic
geant4e, a part of geant4, is used during event reconstruction (not simulation!). It computes the average trajectory of a charged track, assuming a local helix in local magnetic field for each step the covariance matrix along this trajectory due to ❖ multiple scattering ❖ ionization ❖ track curvature |

First Production with the Belle II Distributed Computing System Public
The next generation B factory experiment Belle II will colle ct huge data samples which are a challenge for the computing system. To cope with t he high data volume and rate, Belle II is setting up a distributed computing system b ased on existing technologies and infrastructure, plus Belle II specific extensions for wo rkflow abstraction. The sy… |

Belle Monte-Carlo production on the Amazon EC2 cloud(ISGC) Public
The SuperBelle project to increase the Luminosity of the KEKB collider by a factor 50 will search for Physics beyond the Standard Model through precision measurements and the investigation of rare processes in Flavour Physics. The data rate expected from the experiment is comparable to a current era LHC experiment with commensurate Computing needs… |

Physics Prospects at SuperKEKB / Belle IIPublic
The Belle II Experiment is in its final phase of construction and the SuperKEKB accelerator has successfully completed the first phase of commissioning. With an expected integrated luminosity of 50 ab1 to be collected by the year 2025, the Belle II dataset will allow us to probe New Physics scales that are well beyond the reach of direct producti… |

Track Reconstruction in Belle 2Public
The Silicon Vertex Detector (SVD) of the Belle II experiment is a newly developed device with four measurement layers. The detector is designed to enable track reconstruction down to the lowest momenta possible, in order to significantly increase the effective data sample and the physics potential of the experiment. Both track finding and track fi… |

Status of Belle II/SuperKEKB and plans for dark sector physicsPublic
The next-generation B-factory experiment Belle II at the upgraded KEKB accelerator, SuperKEKB, is aiming to start physics data taking in 2018. It is an asymmetric e+e- collider that will operate with 40x the instantaneous luminosity of KEKB/Belle. The broad physics program includes physics with B and D mesons, muon and tau leptons, measurements us… |

The Data Cache System at the Belle II experimentPublic
At the begging of the Belle experiment, every extracted subset data from full-set data has been stored in “mini-data-structure-table” (mdst) format. However, these files have occupied so much disk space, which causes suffer from the lack of disk space. To solve the problem, Belle experiment composed the extraction of full-set data based on data… |

Challenging the Standard Model - Belle II and the SuperKEKB ProjectPublic
With SuperKEKB and the Belle II experiment a new era of high statistics flavor physics at the Upsilon (4S) resonance is at the horizon, providing almost two orders of magnitude more luminosity compared to the eminently successful B factories PEP II and KEKB. In this presentation we first give a short introduction into the B-meson system and CP vio… |
