高能过程中的横自旋和横动量效应

Transverse-Spin and Transverse-Momentum Effects in High-Energy Processes

Vincenzo Barone, Franco Bradamante, Anna Martin

摘要:

本文综述了硬强子反应中横自旋和横动量现象的研究现状。本文给出了半包容性深部非弹性散射、e^+ e^-湮灭、Drell-Yan产生和强子产生中的单自旋和方位角不对称性的解释。本文的第一部分描述了正在进行的实验和主要的理论框架。第二部分是对实验结果的现象学解释。最后简要讨论了未来测量的前景。

英文摘要:

The state of the art concerning transverse-spin and transverse-momentum phenomena in hard hadronic reactions is reviewed. An account is given of single-spin and azimuthal asymmetries in semiinclusive deep inelastic scattering, e^+ e^- annihilation, Drell-Yan production, and hadroproduction. The ongoing experiments and the main theoretical frameworks are described in the first part of the paper. The second part is devoted to the experimental findings and their phenomenological interpretations. A brief discussion of the perspectives of future measurements is finally presented.
