Physics Prospects at the Next Generation BelleII Experiment — •Jeremy Dalseno — Max-Planck-Institut für Physik, München, Deutschland
The end of the first generation B factory experiments, Belle at KEK and BaBar at SLAC, saw the tremendous success of the Standard Model in the quark flavour sector with the Kobayashi-Maskawa mechanism confirmed as the dominant source of the observed CP violation in Nature. In spite of this, several fundamental questions remain in the flavour sector of quarks and leptons. Some exciting hints of the New Physics that could answer these questions have been found at the B factories, however only a substantial increase in luminosity will greatly enhance the possibility to discover possible new physics effects and identify its nature. We present the prospects on the physics potential of the BelleII experiment which is expected to collect around 50 times the amount of B B pairs as the Belle experiment. This will take place at the SuperKEKB asymmetric-energy e+e− collider with a design luminosity of 8 × 1035 cm−2 s−1, which is around 40 times as large as the peak luminosity achieved by the KEKB collider.
