Abstract | We argue that the s-channel cut contribution to J/psi hadroproduction can be significantly larger than the usual cut contribution of the color-singlet mechanism, which is known to underestimate the experimental measurements. A scenario accounting for intermediate cc[over ] interactions is proposed that reproduces the data at low and midrange transverse momenta P_(T) from the Fermilab Tevatron and BNL Relativistic Heavy Ion Collider. The J/psi produced in this manner are polarized predominantly longitudinally. |
