Search for azimuthal asymmetry of. pi. sup 0 -meson production in beam fragmentation region on polarized protons and deuterons
1989
The inclusive production of {pi}{sup 0}'s in the interaction of unpolarized {pi}{sup {minus}}, {ital k}{sup {minus}}, and antiproton beams with polarized proton and deuteron targets has been studied at IHEP. The absolute value of the asymmetry for {pi}{sup 0} production in the polarized proton and deuteron targets is between zero and fiften percent for large {ital x}={ital P}*/{ital P}*{sub max} and small {ital P}{sub {ital t}} and independent on the quark flavor. Results are presented and compared with theoretical calculations. (AIP)
