Description

The photon-photon final state in the interaction of p-p at √s = 52 GeV has been investigated, detecting the two photons on opposite sides around 900 with respect to the circulating beams of the ISR. In the invariant mass spectrum derived from this configuration no structure is observed above the background. Upper limits for production of narrow resonances decaying into two photons are derived for invariant masses larger than 2.5 GeV/c2. (author)
