Abstract
Single-spin asymmetry A{sub N} of inclusive {pi}{sup 0} production in polarized-target region in the reaction {pi}{sup -} + p{up_arrow} {yields} {pi}{sup 0} + X at 40 GeV is presented. A{sub N} = (-13.8 {+-} 3.8)% at -0.8 < x{sub F} < -0.4 and 1 < p{sub T} < 2 GeV/c and close to zero -0.4 < x{sub F} < -0.1 and 0.5 < p{sub T} < 1.5 GeV/c. Absolute value of asymmetry starts to rise up to the {pi}{sup 0} momentum in the centre-of-mass system close to 1.7 GeV/c for the both central region and target fragmentation region. The asymmetry behavior is similar to the asymmetry measured by the E704 (FNAL, 200 GeV) and STAR (BNL, 20 TeV) Collaborations in the polarized-beam fragmentation region.
