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 $h_1(x,Q^2)$, ${\gamma }_n^{h(1)}$, in the MS scheme of the dimensional regularization. Becau…
