Abstract
We report a new measurement of using a double tag technique, where the hemisphere selection is based on the reconstructed mass of the hadron decay vertex. The measurement was performed using a sample of hadronic events, collected with the SLD detector at SLC. The method utilizes the 3D vertexing abilities of the CCD pixel vertex detector and the small stable SLC beams to obtain a high -tagging efficiency and purity. We obtain .
