论文摘要
在本文中，我们提出了一种通过执行运动学拟合来重建定义$ ep $深度弹性散射的缩放变量的技术。这种重建技术利用了收集的数据的全部潜力。它基于贝叶斯定理，涉及使用信息丰富的先验。 Kinematic Fit方法已在318 GEV中心的中性EP模拟样品中进行了测试，其中$ Q^2 $> 400 GEV $^2 $。除了缩放变量外，该方法还能够估算可能未被发现的可能初始状态辐射（E $_γ$）的能量。在缩放变量重建中，比标准电子和双角技术更好的分辨率是使用运动学拟合来实现的。
In this paper we present a technique to reconstruct the scaling variables defining $ep$ deep inelastic scattering by performing a kinematic fit. This reconstruction technique makes use of the full potential of the data collected. It is based on Bayes Theorem and involves the use of informative priors. The kinematic fit method has been tested for the neutral current ep simulated sample at a center of mass energy of 318 GeV with $Q^2$ > 400 GeV$^2$. In addition to the scaling variables, this method is able to estimate the energy of possible initial state radiation (E$_γ$ ) which otherwise goes undetected. A better resolution than standard electron and double angle techniques in the reconstruction of scaling variables is achieved using a kinematic fit.
