用CDF II探测器寻找全强子末态的希格斯玻色子

Search for the Higgs boson in the all-hadronic final state using the CDF II detector

CDF Collaboration

摘要:

我们报告的搜索生产的希格斯玻色子衰变到两个底夸克伴随着两个额外的夸克。所使用的数据样本对应于CDF II实验记录的在$\sqrt{s}=1.96$ \,TeV处的\ppbar\,碰撞的大约4\,\invfb\,的积分亮度。这次搜索包括两倍于先前发表的结果的积分亮度,使用分析技术来区分来自轻味夸克的喷流和来自胶子辐射的喷流,并增加了对矢量玻色子融合产生的希格斯玻色子玻色子的灵敏度。我们没有发现希格斯玻色子的证据,并在95%的置信水平下,对质量在100\,\gevcc \和150\,\gevcc \之间的希格斯玻色子的希格斯玻色子产生截面进行了限制。对于质量为120的希格斯玻色子,\gevcc,观察到的(预期的)极限是预测的标准模型截面的10.5倍。

英文摘要:

We report on a search for the production of the Higgs boson decaying to two bottom quarks accompanied by two additional quarks. The data sample used corresponds to an integrated luminosity of approximately 4\,\invfb\, of \ppbar\, collisions at $\sqrt{s}=1.96$\,TeV recorded by the CDF II experiment. This search includes twice the integrated luminosity of the previous published result, uses analysis techniques to distinguish jets originating from light flavor quarks and those from gluon radiation, and adds sensitivity to a Higgs boson produced by vector boson fusion. We find no evidence of the Higgs boson and place limits on the Higgs boson production cross section for Higgs boson masses between 100\,\gevcc\, and 150\,\gevcc\, at the 95% confidence level. For a Higgs boson mass of 120\,\gevcc\, the observed (expected) limit is 10.5\,(20.0) times the predicted Standard Model cross section.
