量子统计部分子分布方法中的半包含DIS截面和自旋不对称性

Semiinclusive DIS cross sections and spin asymmetries in the quantum statistical parton distributions approach

Claude Bourrely, Franco Buccella, Jacques Soffer

摘要:

我们考虑的统计部分子分布的扩展,包括它们的横向动量依赖,通过使用两种不同的方法,一种是基于我们的量子统计方法,另一种相对论协变方法。我们考虑了极化分布的Melosh-Wigner旋转的影响。所得结果可与最近的半包容深非弹性散射数据的截面和双自旋不对称性从JLab。对今后的电子-中子散射实验也作了一些预测。

英文摘要:

We consider the extension of the statistical parton distributions to include their transverse momentum dependence, by using two different methods, one is based on our quantum statistical approach, the other on a relativistic covariant method. We take into account the effects of the Melosh-Wigner rotation for the polarized distributions. The results obtained can be compared with recent semiinclusive Deep Inelastic Scattering data on the cross section and double longitudinal-spin asymmetries from JLab. We also give some predictions for future experiments on electron-neutron scattering.
