本文分析了费米实验室Tevatron对撞机D 0实验记录的数据，以寻找与B夸克有关的中性希格斯玻色子。搜索是在三个b夸克通道使用多喷流触发的事件对应于5.2 fb{sup-1}的综合光度。在没有任何显着超出背景的情况下，限制被设置在横截面乘以分支比在希格斯玻色子质量范围90至300 GeV，扩展的最小超对称标准模型的参数空间中的排除区域。
Data recorded by the D0 experiment at the Fermilab Tevatron Collider are analyzed to search for neutral Higgs bosons produced in association with b quarks. The search is performed in the three-b-quark channel using multijet-triggered events corresponding to an integrated luminosity of 5.2 fb{sup -1}. In the absence of any significant excess above background, limits are set on the cross section multiplied by the branching ratio in the Higgs boson mass range 90 to 300 GeV, extending the excluded regions in the parameter space of the minimal supersymmetric standard model.
