B0-meson mixing rediscovery using hadronic b to c transitions at Belle II — •Sviatoslav Bilokin for the Belle II collaboration — Ludwig-Maximilians-Universität München
The Belle II experiment at the SuperKEKB asymmetric energy e+ e− collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is 8× 1035 cm−2s−1 and the Belle II experiment aims to record 50 ab−1 of data, a factor of 50 more than its predecessor. The Belle II collaboration has successfully recorded and processed about 10 fb−1 of data at the Υ(4S) resonance in 2019.
This contribution presents the B0-B0 mixing rediscovery in hadronic B-meson decays using the collected Belle II data. This analysis is a first necessary step towards an improvement of unitarity triangle measurements and New Physics searches in radiative penguin decays.
