T. Gehrmann, QCD CORRECTIONS TO DOUBLE AND SINGLE SPIN ASYMMETRIES IN VECTOR BOSONPRODUCTION AT POLARIZED HADRON COLLIDERS, Nuclear physics. B, 534(1-2), 1998, pp. 21-39
The production of W+/- and Z(0) bosons in collisions of longitudinally
polarized protons allows one to access various combinations of the po
larized quark distributions from the study of double and single spin a
symmetries. We compute the O(alpha(s)) corrections to these asymmetrie
s as function of the vector boson rapidity y in the hadron-hadron cent
re-of-mass frame. Detailed studies of the numerical impact of the next
-to-leading order corrections are presented. The theoretical uncertain
ties of an extraction of polarized quark distributions from future vec
tor boson production data are investigated in detail. (C) 1998 Elsevie
