This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have measured a preliminary value for the branching ratio (Gamma)(D*[sup +][sub s] --> D[sup +][sub s][pi][sup 0])/[Gamma](D*[sup +][sub s] --> D[sup +][sub s][gamma]) = 0.0621 [+-] 0.0049(stat) [+-] 0.0063(syst), which is consistent with the previous measurement, but has higher precision. They have also measured [Gamma](D*[sup 0] --> D[sup 0][pi][sup 0])/[Gamma](D*[sup 0] --> D[sup 0][gamma]) = 1.740 [+-] 0.020(stat) [+-] 0.125(syst), which is more precise than, and in agreement with, the world average. The branching fraction B(D*[sup +][sub s] --> D[sup +][sub s][pi][sup 0]) = 0.0585 [+-] 0.0043(stat) [+-] 0.0056(syst) is larger than the theoretical prediction, which is in the 1-3% range. However, it should be noted that the theory predicts a strong correlation between B(D*[sup +][sub s] --> D[sup +][sub s][pi][sup 0]) and B(D*[sup +] --> D[sup +][gamma]); for B(D*[sup +] --> D[sup +][gamma]) [approx]1%, B(D*[sup +][sub s] -- D[sup +][sub s][pi][sup 0]) is expected to be greatly enhanced.

Available in PDF, EPUB and Kindle. Book excerpt: The authors have measured a preliminary value for the branching ratio?(D*{sub s} --> D+{sub s}?°)/?(D*+{sub s} --> D+{sub s}?) = 0.0621 ± 0.0049(stat) ± 0.0063(syst), which is consistent with the previous measurement, but has higher precision. They have also measured?(D*° --> D°?°)/?(D*° --> D°?) = 1.740 ± 0.020(stat) ± 0.125(syst), which is more precise than, and in agreement with, the world average. The branching fraction B(D*+{sub s} --> D+{sub s}?°) = 0.0585 ± 0.0043(stat) ± 0.0056(syst) is larger than the theoretical prediction, which is in the 1-3% range. However, it should be noted that the theory predicts a strong correlation between B(D*+{sub s} --> D+{sub s}?°) and B(D*+ --> D+?); for B(D*+ --> D+?) ≈1%, B(D*+{sub s} -- D+{sub s}?°) is expected to be greatly enhanced.
