Tensor-polarized twist-3 distribution function of spin-1 deuteron
S. Kumano, Kenshi Kuroki
We investigate the twist-2 and twist-3 tensor-polarized partonic structures of the spin-1 deuteron. Using the operator product expansion with local operators, we derive a Wandzura-…

Tensor-polarized parton distribution functions of the deuteron by a convolution model
S. Kumano, Kenshi Kuroki
Tensor-polarized parton distribution functions (PDFs) are calculated for the deuteron by using a convolution formalism, where the tensor-polarized PDFs are given by the correspondi…

Twist-2 relations for the twist-3 tensor-polarized distribution function of a spin-1 hadron by the operator-product-expansion method
S. Kumano, Kenshi Kuroki
In a spin-1 hadron, tensor-polarized parton distribution functions (PDFs) exist. The twist-2 function is and a twist-3 one is . Because an experiment is under pre…
