Abstract

We present the results for a direct search for light gluinos through the appearance of η→3π⁰ with high transverse momentum in the vacuum tank of the NA48 experiment at CERN. We find one event within a lifetime range of 10^-9-10^-3 s and another one between 10^-10-10^-9 s. Both events are consistent with the expected background from neutrons in the beam, produced by 450 GeV protons impinging on the Be targets, which interact with the residual air in the tank. From these data we give limits on the production of the hypothetical gg̃ bound state, the R⁰ hadron, and its R⁰→ηγ + ̃ decay in the R⁰ mass range between 1 and 5 GeV.
