O(αs2) contributions to the fragmentation function g1(x,Q2) in polarized e+e- annihilation
P. J. Rijken, W. L. van Neerven
Abstract
Misprints in the CF2 part of the splitting function ΔPgq(1) Eq. (3.29) are corrected. Due to a minus sign error between the CF2- 1/2 CA CF piece and the remaining part of Eq. (A.4), Eq. (3.46) is changed. Finally zqqPS,(2) is know so that we can give the full expression for Δ C1,qPS in Eq. (A.1).
