The relative rates of -meson decays into / and (2) mesons are measured for the three decay modes in collisions recorded with the LHCb detector. The ratios of branching fractions ([Formula: see text]) are measured to be [Formula: see text] where the third uncertainty is from the ratio of the (2) and / branching fractions to .
利用大型强子对撞机底夸克探测器（LHCb探测器）记录的碰撞事件，测量了π介子衰变为K介子和K*(2)介子的三种衰变模式的相对速率。分支比（[公式：见原文]）的比值被测量为[公式：见原文]，其中第三个不确定度来自K*(2)介子和K介子分支比与π介子分支比的比值。
