本文导出了核子-核子碰撞中大π介子产生的单横自旋不对称性的计算公式。我们关注的是奇手征贡献，其中横向分布和奇手征自旋独立扭转3分布做出了贡献。这种贡献预计会在xF→−1时产生很大的影响。
A formula for the single transverse spin asymmetry in the large-pTpion production in the nucleon-nucleon collision is derived. We focus on the chiral-odd contribution where the transversity distribution and the chiral-odd spin-independent twist-3 distribution contributes. This contribution is expected to give rise to a large effect at xF→−1.
