Study of direct CP-violation in B → K π with Belle II - Overview and Prospects — •Benedikt Wach for the Belle 2 collaboration — Max-Planck-Institut fuer Physik, Muenchen, Deutschland

Although the Standard Model (SM) is an established and well-tested theory, mysteries such as the matter-antimatter-asymmetry call for new physics lying beyond. The Belle II experiment will help to test theoretical predictions, provide necessary experimental input and look for non-SM phenomena.

With an expected integrated luminosity 50 times that of its precursor Belle, the Belle II experiment will allow to measure the flavor dynamics of B-meson decays with unprecedented precision.

Charmless B meson decays to K-π final states represent a powerful tool to better understand B decay mechanisms and further provide excellent sensitivity for new physics, in particular, phenomena related to CPV.

An overview of the basic concepts of charge-parity violation (CPV) in the B meson sector is given, focusing on neutral and charged B → K π decay channels. Furthermore, a prospect for Belle II is provided, taking into account the expected increase in integrated luminosity.
