在CDF寻找双光子事件和额外的高能物体的异常产生

Search for Anomalous Production of Events with Two Photons and Additional Energetic Objects at CDF

The CDF Collaboration

摘要:

我们目前的搜索结果的异常生产的两个光子连同一个电子,μ子,$τ$轻子,丢失的横向能量,或使用$p\bar{p}$碰撞数据从1.1-2.0 FB $^{-1}$的积分亮度收集在费米实验室(CDF)。事件产量和运动学分布检查新物理的迹象,而不赞成一个特定的新物理模型。结果与标准模型的预期一致。搜索采用了几种新的分析技术,显着减少仪器背景的电子和丢失的横向能量通道。

英文摘要:

We present results of a search for anomalous production of two photons together with an electron, muon, $τ$ lepton, missing transverse energy, or jets using $p\bar{p}$ collision data from 1.1-2.0 fb$^{-1}$ of integrated luminosity collected by the Collider Detector at Fermilab (CDF). The event yields and kinematic distributions are examined for signs of new physics without favoring a specific model of new physics. The results are consistent with the standard model expectations. The search employs several new analysis techniques that significantly reduce instrumental backgrounds in channels with an electron and missing transverse energy.
