We report on the decay to two photons of the Full-size image (<1 K) charmonium resonance formed in Full-size image (<1 K) interactions at Fermilab experiment E835. We have measured the product of branching ratios Full-size image (<1 K). Using values from the 2002 PDG, this measurement leads to the partial width Γ(χc0→γγ)=2.9±0.9 keV.

Abstract

We report on the decay to two photons of the Full-size image (<1 K) charmonium resonance formed in Full-size image (<1 K) interactions at Fermilab experiment E835. We have measured the product of branching ratios Full-size image (<1 K). Using values from the 2002 PDG, this measurement leads to the partial width Γ(χc0→γγ)=2.9±0.9 keV.
