光子+喷流的异常产生

Search for Anomalous Production of Photon+Jets

Samantha K. Hewamanage

摘要:

许多新的物理模型预测了可能产生光子和喷流特征的机制。我们在光子+射流通道中搜索,独立于任何模型,使用CDF运行II在费米实验室Tevatron收集的数据,从p-pbar碰撞在质心能量为1.96 TeV的新物理。应用各种技术来估计标准模型期望和非碰撞背景。我们检查几个运动学分布,包括横向能量的光子和不变质量的差异与标准模型。

英文摘要:

Many new physics models predict mechanisms that could produce a photon and jets signature. We search in the photon + jets channel, independent of any model, for new physics using CDF Run II data collected at the Fermilab Tevatron from p-pbar collisions at a center of mass energy of 1.96 TeV. A variety of techniques are applied to estimate the standard model expectation and non-collision backgrounds. We examine several kinematic distributions including transverse energy of the photon and invariant masses for discrepancies with the standard model.
