%0 Journal Article %T Advances in Delta-md measurements %A Frederic Jean Ronga %J Physics %D 2003 %I arXiv %X We report the current status of Delta-md measurements at B-factories. The most recent world average is Delta-md = 0.502+-0.007 1/ps (1.4% accuracy). An estimate of the errors for 500 1/fb data is also given. %U http://arxiv.org/abs/hep-ex/0306061v2
