Direct search for light gluinos
We present the results for a direct search for light gluinos through the appearance of with high transverse momentum in the vacuum tank of the NA48 experiment at CERN. We find one event within a lifetime range of s and another one between 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 bound state, the hadron, and its decay in the mass range between 1 and 5~GeV
Direct search for light gluinos
We present the results for a direct search for light gluinos through the appearance of eta --> 3 pi0 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 gg~ bound state, the R0 hadron, and its R0 --> eta gamma~ decay in the R0 mass range between 1 and 5 GeV
Direct search for light gluinos RID A-4071-2012
We present the results for a direct search for light gluinos through the appearance of eta --> 3 pi(0) 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 g (g) over tilde bound state, the R-0 hadron, and its R-0 --> eta decay in the R-0 mass range between 1 and 5 GeV.

Direct search for light gluinos
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. © 1999 Elsevier Science B.V.
