N2 - The charmed quark charge asymmetry has been measured at the average centre of mass energy of 35 GeV with the JADE detector at thee + e − storage ring PETRA. Charmed quarks were identified byD *± tagging using the ΔM technique.D *± mesons were reconstructed through their decay intoD 0 mesons resulting in (Kπ) π and (K π π π) π final states. The measured charge asymmetryA=−0.149±0.067 is in agreement with the expectation from the electroweak interference effect in quantum flavour dynamics (QFD).
