Abstract

We remind the origin of the proton spin problem in deep inelastic scattering, then discuss the recent RHIC data and demonstrate that complementing the RHIC data with theoretical calculations in double-logarithmic approximation solves the proton spin problem even when contributions of the angular orbital momentum of the partons are not taken into account.

质子自旋问题的现状

我们回顾了深度非弹性散射中质子自旋问题的起源，然后讨论了最近的RHIC数据，并证明了在双对数近似中补充RHIC数据和理论计算可以解决质子自旋问题，即使不考虑部分子的角轨道动量的贡献。

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
