Abstract

From e+e- collision data acquired with the CLEO detector at the Cornell Electron Storage Ring, we observe the non-DD̄ decay ψ(3770) →γχc1 with a statistical significance of 6.6 standard deviations, using the two-photon cascades to J/ψ and J/ψ→+-. We determine σ(e+e-→ψ(3770))×B(ψ(3770)→γχc1)=(18. 0±3.3±2.5)pb and branching fraction B(ψ(3770) →γχc1)=(2.8±0.5±0.4)×10-3. We set 90% C.L. upper limits for the transition to χc2 (χc0): σ×B<5.7pb (<282pb) and B<0.9×10-3 (<44×10-3). We also determine Γ(ψ(3770)→γχc1)/Γ(ψ(3770)→π+π-J/ ψ)=1.5±0.3±0.3 (>1.0 at 90% C.L.), which bears upon the interpretation of X(3872).
