Comments on glueballinos (R0 particles) and R0 searches
  We propose a search strategy for the light R0 (glueballino) particle suggested by G.Farrar in connection with the light gluino scenario. The basic idea is to moderate and stop the R0 particles and then observe their decay to almost monochromatic pions - at an appropriate time delay relative to a primary collision event, where a gluino jet, likely to fragment into the R0, was produced. This technique is optimized at colliders and depends on qualitative features of the R0 hadronic interactions which we discuss in detail.
