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…
Parametrization of polarized parton distribution functions
M. Hirai
Polarized parton distribution functions are determined by using asymmetry A_1 data from longitudinally polarized deep inelastic scattering experiments. From our χ^2 analysis, polar…
Two-loop anomalous dimensions for the structure function h1
S. Kumano, M. Miyama
Chiral-odd structure function h1 is expected to be measured in polarized Drell-Yan process. We calculate two-loop anomalous dimensions for h1 in the minimal subtraction scheme. Dim…
Numerical solution of Q^2 evolution equations for polarized structure functions
M. Hirai, S. Kumano, M. Miyama
We investigate numerical solution of Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) Q^2 evolution equations for longitudinally polarized structure functions. Flavor nonsinglet…
