Abstract
We study contributions from color-octet quarkonium formation mechanism s to J/psi hadroproduction at low rho(perpendicular to). We include tr ansitions of color-octet <c(c)over bar> states into ''direct'' J/psi a nd into chi(1,2) which decay radiatively into a J/psi. The leading col or-singlet mechanisms analyzed in earlier work and the leading color-o ctet mechanisms discussed here are found to be insufficient to reprodu ce the p(perpendicular to)-integrated J/psi production data.
