Analysis of the dacay channel B0 → ψ(2S) π0 with Belle — •Elena Nedelkovska, Jeremy Dalseno, and Christian Kiesling — Max-Planck Intitut fuer Physik, Muenchen
The Belle experiment is an asymmetric e+e− collider, which was taking data at the KEKB accelerator untill June 2010. It is still the world’s highest luminosity machine with a record instantenous luminosity of 2.11 × 1034 cm−2s−1. Most data at Belle is collected at the Y(4S) resonance, which exclusively decays into B meson pairs. Measurement of the channel B0 → ψ (2S) π 0 will give access to penguin contributions of the decay amplitude. The status of the analysis is presented.
