TOWARDS FIRST PHYSICS AT BELLE II

The next-generation B-factory Belle II at the upgraded KEKB accelerator, SuperKEKB, is aiming to start physics data taking in 2018. The broad physics program covers e.g. physics with B and D mesons, mu and tau leptons as well as measurements using the method of radiative returns and direct searches for New Physics. Among these analyses, there is the search for a Dark Photon decaying into light dark matter or leptons, and the precision measurement of the muon pair asymmetry that both have demanding requirements for the trigger system and the latter also for precision QED theory.
