Matching between Collinear Twist-3 and TMD Fragmentation Function Contributions to Polarized Hyperon Production in SIDIS
Riku Ikarashi, Yuji Koike, Shinsuke Yoshida
We investigate the consistency between the collinear twist-3 factorization and the transverse-momentum-dependent (TMD) factorization for the transversely polarized hyperon producti…

A New Derivation of the Twist-3 Gluon Fragmentation Contribution to Polarized Hyperon Production
Riku Ikarashi, Yuji Koike, Kenta Yabe +1
A novel method of formulating the twist-3 gluon fragmentation function contribution to hyperon polarization in the proton-proton collision is presented. The method employs a covari…

Twist-3 Gluon Fragmentation Contribution to Hyperon Polarization in Semi-Inclusive Deep Inelastic Scattering
Riku Ikarashi, Yuji Koike, Kenta Yabe +1
We derive the twist-3 gluon fragmentation function (FF) contribution to the transversely polarized hyperon production in semi-inclusive deep inelastic scattering, $ep\to eΛ^\uparro…
