Description

Twist-3 gluon fragmentation function contribution to the transversely polarized hyperon production in the unpolarized proton-proton collision, pp → Λ↑X, is formulated within the collinear factorization and the corresponding cross section is calculated in the leading order (LO) with respect to the QCD coupling constant. This has completed the LO cross section for this process. It is also shown that the QCD equation-of-motion relation and the Lorentz invariance relations are crucial to guarantee the frame independence of the cross section. The formula is relevant for the ongoing RHIC experiment. (author)
