Abstract

In the near future, the Jefferson Lab \(b_1\) experiment will provide the second measurement of tensor polarized asymmetries in inclusive DIS on the deuteron. In this asymmetry, 4 independent tensor polarized structure functions contribute. This necessitates systematic approximations in the extraction of the leading twist structure function \(b_1\) from a single tensor asymmetry measurement. Contamination from higher twist structure functions and kinematic effects is discussed here. Using a deuteron convolution model, we quantify the systematic errors from these approximations for two different choices for the target polarization direction (momentum transfer, electron beam direction). For Jefferson Lab 12 GeV kinematics, the systematic error turns out to be comparable between the two polarization options, while at higher \(Q^2\) values the momentum transfer direction is preferred.

偏振选项在包容性DIS关闭张量极化氘核
在不久的将来,杰斐逊实验室\(b_1\)实验将提供第二次测量氘子上包含DIS的张量偏振不对称。在这种不对称性中,有4个独立的张量极化结构函数。这需要在从单个张量不对称测量中提取导扭结构函数\(b_1\)时进行系统的近似。本文讨论了高扭结构函数的污染和运动学效应。利用氘核卷积模型,我们量化了两种不同的目标极化方向(动量传递,电子束方向)的系统误差。对于Jefferson Lab 12gev运动学,两种极化选项之间的系统误差是相当的,而在更高的\(Q^2\)值下,动量传递方向是首选的。
