Abstract

I present preliminary results on the search for hc in its ηcγ and J/ψπ0 decay modes. We observe an excess of ηcγ events near 3526 MeV that has a probability P ∼ 0.001 to arise from background fluctations. The resonance parameters are M = 3525.8±0.2±0.2 MeV, Γ ≤ 1 MeV, and 10.6±3.7±3.4(br) < Γp̄pBηcγ < 12.8±4.8±4.5 (br) eV. We find no event excess within the search region in the J/ψπ0 mode. © 2005 Elsevier B.V. All rights reserved.
