Abstract

The charmed quark charge asymmetry has been measured at the average centre of mass energy of 35 GeV with the JADE detector at the e⁺e^- storage ring PETRA. Charmed quarks were identified by D^*± tagging using the ΔM technique. D^*± mesons were reconstructed through their decay into D⁰ mesons resulting in (Kπ) π and (K π π π) π final states. The measured charge asymmetry A=-0.149±0.067 is in agreement with the expectation from the electroweak interference effect in quantum flavour dynamics (QFD).
