本文描述了在质心能质子-反质子碰撞中，衰变模中的介子与衰变模中的介子的截面与分支分数之比的测量。测量是基于完整的CDF Run II数据集，该数据集来自积分光度。对于横向动量大于，快度小于0.6的介子，其产生截面与分支分数之比为。使用已知的分支分数，knownproduction横截面，和选择的predictedbranching分数，总生产横截面的范围估计。
We describe a measurement of the ratio of the cross sections times branching fractions of themeson in the decay modeto themeson in the decay modein proton-antiproton collisions at center-of-mass energy. The measurement is based on the complete CDF Run II data set, which comes from an integrated luminosity of. The ratio of the production cross sections times branching fractions forandmesons with momentum transverse to the beam greater thanand rapidity magnitude smaller than 0.6 is. Using the knownbranching fraction, the knownproduction cross section, and a selection of the predictedbranching fractions, the range for the totalproduction cross section is estimated.
