J/psi Pair Production at the Tevatron | Cong-Feng Qiao
; | Date: |
10 Jun 2002 | Journal: | Phys.Rev. D66 (2002) 057504 | Subject: | hep-ph | Affiliation: | Hiroshima University | Abstract: | The double J/psi production in par{p} collision is revisited. It is found that the J/psi pair production rate at leading order with p_T > 4 GeV in conventional scheme is larger than the rate derived from color-octet mechanism by a factor of five. As the double J/psi production is shown to be attainable with data yet collected at the Tevatron detectors, experimental study on it would be helpful to clarify the validity of the conventional color-singlet description for heavy quarkonium production. | Source: | arXiv, hep-ph/0206093 | Services: | Forum | Review | PDF | Favorites |
