Dalitz analysis on B⁺→ K_S⁰π⁺π⁰ — •Oskar Tittel — Max-Planck-Institut für Physik, München

The Belle II experiment in Tsukuba, Japan, is working at the high-intensity frontier of the search for physics beyond the Standard Model (SM). A direct test of the SM is the verification of the so-called "isospin sum-rule" in the B→ K^*π system, which depends on the branching fractions (BF’s) and the direct CP asymmetries of all B→ K^*π decay modes. These quantities can be extracted from Dalitz analyses on the decay channels B⁰→ K⁺π⁻π⁰ and B⁺→ K_S⁰π⁺π⁰.

I will present the Belle II experiment, introduce the isospin sum rule and show the current state of the analysis on B⁺→ K_S⁰π⁺π⁰.
