标题： B Hadron Production and b-bbar Correlations in Z0 Decays at SLD

摘要： 我们提出了三项SLD分析的结果：我们最终确定的胶子分裂为b-bbar的比率，Z0衰变中含b夸克强子产生过程的改进测量，以及Z0衰变中两个领先B强子之间的能量关联的初步首次测量。 我们的结果是基于1996年至1998年在斯坦福直线对撞机（SLC）利用正负电子湮灭产生的强子\z 0衰变，并在SLC大探测器（SLD）中收集的数据。 在这段时间内，我们使用了具有宽接受角和优秀的入射参数分辨率的升级版顶点探测器，从而显著提高了我们对低能B强子的标记能力。 显示英文摘要

摘要： We present results of three SLD analyses: our final determination of the rate of gluon splitting into b-bbar, an improved measurement of the inclusive b quark fragmentation function in Z0 decays, and a preliminary first measurement of the energy correlation between the two leading B hadrons in Z0 decays. Our results are obtained using hadronic \z0decays produced in e+e- annihilations at the Stanford Linear Collider (SLC) between 1996 and 1998 and collected in the SLC Large Detector (SLD). In this period, we used an upgraded vertex detector with wide acceptance and excellent impact parameter resolution, thus improving considerably our tagging capability for low-energy B hadrons.
