R-hadron

R-hadrons are hypothetical particles composed by a Supersymmetric particle and at least one quark.

Only a few of the current SUSY theories predict the existence of R-hadrons, since in most of the parameter space all the supersymmetric particles are so separated in mass that their decays are very fast (with the exeption of the LSP, which is stable in all the SUSY theories with R-parity).

R-hadrons are possible when a coloured (in the sense of QCD) supersymmetric particle (e.g., a gluino or a squark) has a mean lifetime longer than the typical hadronization time scale, and so QCD bound states are formed with ordinary partons (quarks and gluons), in analogy with the ordinary hadrons.

One example of a theory predicting observable R-hadrons is Split SUSY. Its main feature is, in fact, that all the new bosons be at a very high mass scale, and only the new fermions at the TeV scale,
