| Abstract | A search has been made at the CERN ISR for long-lived non-annihilating particles of two types: those which exhibit strong interactions and those which do not (heavy leptons). Invariant cross section upper limits of 6 nb GeV/sup -2/ and 1.8 nb GeV/sup -2/ were measured for these two classes of particles, respectively, for particle masses close to the anti-deuteron mass. Upper limits are also placed on the production of new particles with masses in the range 1.4 to 3.0 GeV, and invariant cross sections are quoted for pi , p, d production. The experiment was performed at square root s=53 GeV with x (=2p/sub L// square root s) in the range 0.07 to 0.15 and p/sub T/ between 0.08 and 0.16 GeV/c. Antideuterons were identified by annihilation in a 1.4 m /sup 3/ scintillation calorimeter. (19 refs). |
