再论横动量相关的统计部分子分布

The transverse momentum dependent statistical parton distributions revisited

Claude Bourrely, Franco Buccella, Jacques Soffer

摘要:

通过考虑质子靶具有有限的纵向动量,重新审视了统计部分子分布的扩展,包括它们的横向动量依赖性(TMD)。TMD将通过横向能量求和规则产生。新的结果主要与低$Q^2$区的电子-质子非弹性碰撞有关。我们考虑了Melosh-Wigner旋转对螺旋度分布的影响。

英文摘要:

The extension of the statistical parton distributions to include their transverse momentum dependence (TMD) is revisited by considering that the proton target has a finite longitudinal momentum. The TMD will be generated by means of a transverse energy sum rule. The new results are mainly relevant for electron-proton inelastic collisions in the low $Q^2$ region. We take into account the effects of the Melosh-Wigner rotation for the helicity distributions.
