Hadron Structures and Perturbative QCD

Yuji Koike

In the first part of this talk, I will summarize recent developments in the study of the chiral-odd spin-dependent parton distributions h_1(x,Q^2) and h_L(x,Q^2) of the nucleon, in…

NLO $Q^{2}$ -evolution of the nucleon's transversity distribution $h_{1} (x, Q^{2})$

A. Hayashigaki, Y. Kanazawa, Yuji Koike

We present a calculation of the two-loop anomalous dimension for the transversity distribution $h_{1} (x, Q^{2})$ , $γ_{n}^{h (1)}$ , in the MS scheme of the dimensional regularization. Becau…

$Q^{2}$ dependence of chiral-odd twist-3 distribution $e (x, Q^{2})$

Y. Koike, N. Nishiyama

We discuss the $Q^{2}$ dependence of the chiral-odd twist-3 distribution $e (x, Q^{2})$ . The anomalous dimension matrix for the corresponding twist-3 operators is calculated in the one-l…
