J/{psi} spin asymmetries in the color-octet model
- Theory Group, Tata Institute of Fundamental Research, Homi Bhabha Road, Bombay 400005 (India)
We investigate the pattern of asymmetries in the color-octet model for inclusive production of charmonium with polarized initial state hadrons and photons. The double polarized asymmetry for J/{psi} involves a new combination of long-distance matrix elements. We also investigate the asymmetries for {eta}{sub c}, {chi}{sub c}, and {Upsilon} production. The asymmetries distinguish well between different models of charmonium production. {copyright} {ital 1997} {ital The American Physical Society}
