Study of D⁰ → π⁺ π⁻ π⁺ π⁻ at Belle — •Johannes Rauch — Technische Universität München

Singly Cabibbo suppressed decays of charm mesons are expected to show a very small CP asymmetry, if any, in the Standard Model. Therefore, these channels provide a good probe for new physics. Spectroscopy of various decay channels in multi-hadronic states have seldomly been undertaken in the current era of large data sets provided e.g. by the Belle experiment. We will present the current status of an analysis of D⁰ → π⁺ π⁻ π⁺ π⁻. Preliminary results of event selection and partial wave analysis will be shown.
