Query: Experimental and Cosmological Implications of Light Gauginos   Gauginos may be nearly massless at tree level, with loop corrections giving a
gluino mass of order 100 MeV and a photino mass of order 1 GeV. Relic photinos
can naturally account for the observed dark matter, but their detection is more
difficult than for conventional WIMPs. The lightest gluino-containing baryon
could account for the recently observed ultra-high energy cosmic rays, which
violate the GZK bound. The predicted mass and properties of the gluino-gluino
boundstate agree with those of the eta(1410), a flavor singlet pseudoscalar
meson which has proved difficult to reconcile with QCD predictions. Laboratory
experiments presently exclude only a small portion of the interesting parameter
space, although improvements expected in the next year may lead to complete
exclusion or discovery.
