Measurement of 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})
Abstract
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.
