共振区和DIS区的氘核自旋结构函数

Deuteron spin structure functions in the resonance and DIS regions

S. A. Kulagin, W. Melnitchouk

摘要:

在核脉冲近似下,我们导出了自旋相关的核和核子g_1和g_2结构函数之间的关系,这些关系在所有Q^2、共振区和深非弹性区都是有效的。我们将这种形式应用于氘的特殊情况,氘通常被用作中子结构信息的来源,并比较了使用精确运动学和使用适用于大Q ^2的近似计算的核修正的大小。

英文摘要:

We derive relations between spin-dependent nuclear and nucleon g_1 and g_2 structure functions within the nuclear impulse approximation, which are valid at all Q^2, and in both the resonance and deep inelastic regions. We apply the formalism to the specific case of the deuteron, which is often used as a source of neutron structure information, and compare the size of the nuclear corrections calculated using exact kinematics and using approximations applicable at large Q^2.
