This book was released on 2005 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data samples corresponding to the isospin-violating decay D*{sub s} → D{sub s}+?° and the decays D*{sub s}+ → D{sub s}+, D*° → D°?° and D*° → D°? are reconstructed using 90.4 fb−1 of data recorded by the BABAR detector at the PEP-II asymmetric-energy e+e− collider. The following branching ratios are extracted:?(D*{sub s}+ → D{sub s}+?°)/?(D*{sub s}+ → D{sub s}+?) = 0.062 ± 0.005(stat.) ± 0.006(syst.) and?(D*° → D°?°)/?(D*° → D°?) = 1.74 ± 0.02(stat.) ± 0.13(syst.). Both measurements represent significant improvements over present world averages.
