14 Oct 2004 | Journal: | Phys.Rev.Lett. 94 (2005) 032004 | Subject: | hep-ex | Abstract: | We report on a search for the recently reported X(3872) state using 15.1 fb^{-1} e+ e- data taken in the sqrt{s} = 9.46-11.30 GeV region. Separate searches for the production of X(3872) in untagged gamma-gamma fusion and e+ e- annihilation following initial state radiation (ISR) are made by taking advantage of the unique correlation of J/psi -> l+ l- in X(3872) decay to pi+ pi- J/psi. No signals are observed in either case, and 90% confidence upper limits are established as (2J+1)Gamma_{gammagamma}B(X -> pi+ pi- J/psi) < 12.9 eV and Gamma_{ee}B(X -> pi+ pi- J/psi) < 8.3 eV. | Source: | arXiv, hep-ex/0410038 | Services: | Forum | Review | PDF | Favorites |
