Using a sample of four million hadronic Z events collected in ALEPH from 1991 to 1995, the decays D∗+→D0πs+, with D0 decaying to K−π+ or to K+π−, are studied. The relative branching ratio B(D0→K+π−)/B(D0→K−π+) is measured to be 1.84±0.59(stat.) ±0.34(syst.)%. The two possible contributions to the D0...
