在具有标量粒子的人工色模型下计算了遍举衰变b→Xsγ的O(αs)修正 .发现当使用ALEPH实验数据时 ,此模型预言的衰变宽度可以减少到标准模型值的 5 0 % .CLEO实验下限与标准模型值相比较减少了 33% ,它比B→B混合对此模型参数空间的限制更严 .此模型预言的b→Xsγ分支比在部分参数空间上与标准模型有大的偏差 ,有望在即将投入运行的升级CLEO探测器和B介子工厂上观察到 The O (αs) correction of ubiquitous decay b → Xsγ was calculated under the artificial color model with scalar particles. The decay width predicted by this model can be reduced to 50% of the standard model value when using ALEPH experimental data.CLEO The experimental lower limit is 33% less than the standard model value, which is more restrictive than the B → B mixture in the parameter space of this model. The b → Xs γ branch ratio predicted by this model deviates from the standard model in part of the parameter space , Is expected to be observed on the upgraded CLEO detector and B-messenger plant that is about to go into operation
