在1.96 TeV与高pT轻子的p-pbar碰撞中寻找电荷中性伴子的产生

Search for chargino-neutralino production in p-pbar collisions at 1.96 TeV with high pT leptons

CDF Collaboration, T. Aaltonen

摘要:

我们提出了一个搜索的相关生产charginos和neutralinos在p-pbar碰撞在1.96 TeV。这些数据是在费米实验室的对撞机探测器(CDF II)上收集的,对应的积分亮度在0.7到1.0 fb-1之间。我们寻找一个高pT电子或μ子,和两个额外的轻子的最终状态。我们的结果与标准模型的预期是一致的,我们设置的截面的电荷子质量的函数在三个不同的超对称的情况下的限制。对于没有slepton混合的特定MSSM场景,我们设置95% C.L. 151 GeV/c^2。

英文摘要:

We present a search for the associated production of charginos and neutralinos in p-pbar collisions at 1.96 TeV. The data were collected at the Collider Detector at Fermilab (CDF II) and correspond to integrated luminosities between 0.7 and 1.0 fb-1. We look for final states with one high pT electron or muon, and two additional leptons. Our results are consistent with the standard model expectations, and we set limits on the cross section as a function of the chargino mass in three different supersymmetric scenarios. For a specific MSSM scenario with no slepton mixing we set a 95 % C.L. limit at 151 GeV/c^2.
