Search for New Physics in Singly Cabbibo Suppressed D Decays at the Belle Experiment — •Dmytro Levit, Daniel Greenwald, Johannes Rauch, and Staphan Paul — Physikdepartment E18, Technische Universität München, Garching, Deutschland

The Standard Model predicts CP-Violation effects to be confined to ΔI = 1/2 amplitudes in singly Cabibbo suppressed D decays. Therefore the measurement of CP violation in ΔI = 3/2 amplitudes will provide evidence of new physics.

In our analysis we undertake the first measurement of the branching ratio for the D^± → K_s⁰ K^∓ π^± π^± π⁰ decay using the data sample of the Belle experiment. Additionally an amplitude analysis of the decay will be performed to estimate the effect of the new physics contribution to the decay.

The current status of the first step of the analysis, the branching ratio measurement, will be presented in the contribution.
