Description
We argue that the s-channel cut contribution to J/ψ 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 interactions is proposed that reproduces the data at low and midrange transverse momenta PT from the Fermilab Tevatron and BNL Relativistic Heavy Ion Collider. The J/ψ produced in this manner are polarized predominantly longitudinally
