顶对不变质量分布:新物理学的窗口

Top pair invariant mass distribution: a window on new physics

R. Frederix, F. Maltoni

摘要:

我们详细探讨了测量ttbar不变质量分布的物理潜力。首先,我们评估了这个可观测的最佳预测的准确性,发现在低不变质量区域,形状是非常好的预测,可以用来执行顶部质量测量。其次,我们研究了重s通道共振对ttbar不变质量分布的影响,在一个模型无关的方式。我们提供了必要的蒙特卡罗工具来执行搜索,并概述了一个简单的三步分析。

英文摘要:

We explore in detail the physics potential of a measurement of the ttbar invariant mass distribution. First, we assess the accuracy of the best available predictions for this observable and find that in the low invariant mass region, the shape is very well predicted and could be used to perform a top mass measurement. Second, we study the effects of a heavy s-channel resonance on the ttbar invariant mass distribution, in a model independent way. We provide the necessary Monte Carlo tools to perform the search and outline a simple three-step analysis.
