摘要

摘要这项工作提出了一种测量强子对撞机产生的射流样品中的胶子射流分数的新方法。该方法使用夸克/胶子模型模板--夸克和胶子射流在射流宏参数上的分布。在这种方法的框架内，可以找到与模型夸克/胶子模板与真实模板的偏差相关的测量不确定性模型。讨论了数据对模型夸克/胶子模板的修正问题。

Model Uncertainty in Measuring the Gluon Jet Fraction at the Hadron Collider

The work proposes a new method for measuring the gluon jet fraction in jet sample produced at the hadron collider. This method uses model quark/gluon templates—distributions of quark and gluon jets over the jet macro parameter. Within the framework of this method, it is possible to find a model uncertainty of measurement associated with the deviation of model quark/gluon templates from the true ones. The issue of data-motivated corrections to the model quark/gluon templates is discussed.
