介子产生的总截面和微分截面，乘以它们的分支分数to，是相对于介子产生的总截面和微分截面，乘以它们的分支分数to来测量的。用于这项研究的数据对应于2012年大型强子对撞机ATLAS探测器在质心能量为的情况下记录的碰撞积分光度。测量是在横向动量箱和速度箱中分别进行的.全范围内的相对横截面乘以分支分数为。差分测量表明，的产生截面的下降速度比的产生截面，而没有观察到显着的依赖于快度。
The total cross section and differential cross sections for the production ofmesons, times their branching fraction to, are measured relative to those for the production ofmesons, times their branching fraction to. The data used for this study correspond to an integrated luminosity ofofcollisions recorded by the ATLAS detector at the Large Hadron Collider in 2012 at a center-of-mass energy of. The measurement is performed differentially in bins of transverse momentumforandand in bins of rapidityforand. The relative cross section times branching fraction for the full rangeandis. The differential measurements suggest that the production cross section of thedecreases faster withthan the production cross section of the, while no significant dependence on rapidity is observed.
