Abstract
Using the ARGUS detector at thee + e − storage ring DORIS II at DESY, a study ofB 0 \(\bar B^0 \) oscillations has been performed using three different techniques. Besides the standard dilepton method, charge correlations betweenD * mesons and one or two leptons have also been investigated. The mixing parameterr is determined to be (20.6±7.0)%.
