深部非弹性ep碰撞中性电流事件的运动学拟合

Kinematic fitting of Neutral current events in deep inelastic ep collisions

Ritu Aggarwal, Allen Caldwell

摘要:

在本文中,我们提出了一种技术来重建的尺度变量定义$ep$深非弹性散射进行运动学拟合。这种重建技术充分利用了所收集数据的潜力。它是基于贝叶斯定理,并涉及使用信息先验。对质心能量为318 GeV,$Q^2$ > 400 GeV $^2$的中性流ep模拟样品进行了运动学拟合。除了标度变量之外,该方法还能够估计可能的初始状态辐射(E $_γ$)的能量,否则未被检测到。一个更好的分辨率比标准的电子和双角度技术在重建的标度变量实现了使用运动学拟合。

英文摘要:

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.
