在CDF上寻找模拟标准模型顶事件签名的超对称顶夸克对产生

Search for Pair Production of Supersymmetric Top Quarks Mimicking Standard Model Top Event Signatures at CDF

Andrew G. Ivanov

摘要:

我们目前的搜索结果的超对称的合作伙伴的顶夸克,停止夸克,衰变到一个b-夸克和电荷伴随着随后的电荷衰变成中性伴子,轻子和中微子。利用Tevatron对撞机CDF探测器收集的对应于2.7 inv fb的积分亮度的数据样本,重建了候选事件的停止质量,并设定95% C. L.终止夸克、电荷伴子和中性伴子的质量上限以及电荷伴子与中性伴子+轻子+中微子的分支比。

英文摘要:

We present results of the search for the super-symmetric partner of the top quark, the stop quark, decaying to a b-quark and chargino with the subsequent chargino decay into a neutralino, lepton and neutrino. Using the data sample corresponding to 2.7 inv fb of integrated luminosity, collected with the CDF Detector of the Tevatron collider, we reconstruct the stop mass of candidate events and set 95% C. L. upper limits on masses of the stop quark, chargino and neutralino and the branching ratio of chargino to neutralino+lepton+neutrino.
