Higher-Twist Effects on the Nucleon Spin Structure Functions in the Small Q2 Range

  • Based on the quark model, the Q2 evolution of the nucleon spin structure functions in the small Q2 region is calculated. The higher-twist effects a2(Q2) and d2(Q2) are investigated. Comparison with other model calculations is also proceeded.

Higher-Twist Effects on the Nucleon Spin Structure Functions in the Small Q2 Range

  • Institute of High Energy Physics, CAS, Beijing 100039, China

Abstract: Based on the quark model, the Q2 evolution of the nucleon spin structure functions in the small Q2 region is calculated. The higher-twist effects a2(Q2) and d2(Q2) are investigated. Comparison with other model calculations is also proceeded.
