用全CDF数据集搜索与顶夸克有关的标准模型希格斯玻色子

Search for the standard model Higgs boson produced in association with top quarks using the full CDF data set

The CDF Collaboration

摘要:

本文利用费米实验室对撞机探测器收集的完整的Run II质子-反质子碰撞数据集(对应于9.45逆fb),对与顶夸克有关的标准模型希格斯玻色子进行了搜索。没有观察到超过预期背景的显著过量,并且95%的能级上限被放置在截面σ上(t \bar{t} H -->轻子+缺失的横向能量+喷流)。对于质量为125 GeV的希格斯玻色子,我们期望设定12.6的极限,并观察到标准模型速率的20.5倍的极限。这是迄今为止在该通道中对标准模型希格斯玻色子最敏感的搜索。

英文摘要:

A search is presented for the standard model Higgs boson produced in association with top quarks using the full Run II proton-antiproton collision data set, corresponding to 9.45 inverse fb, collected by the Collider Detector at Fermilab. No significant excess over the expected background is observed, and 95% credibility-level upper bounds are placed on the cross section sigma(t\bar{t}H --> lepton + missing transverse energy + jets). For a Higgs boson mass of 125 GeV, we expect to set a limit of 12.6, and observe a limit of 20.5 times the standard model rate. This represents the most sensitive search for a standard model Higgs boson in this channel to date.
