Charm-sea Contribution to High-p_T psi Production at the Fermilab Tevatron | Cong-Feng Qiao
; | Date: |
25 Feb 2002 | Subject: | hep-ph | Affiliation: | Hiroshima Uni. | Abstract: | The direct production of $J/psi(psi’)$ at large transverse momentum, $p_T gg M_{J/psi}$, at the Fermilab Tevatron is revisited. It is found that the sea-quark initiated processes dominate in the high-$p_T$ region within the framework of color-singlet model, which is not widely realized. We think this finding is enlightening for further investigation on the charmonium production mechanism. | Source: | arXiv, hep-ph/0202227 | Services: | Forum | Review | PDF | Favorites |
