Phenomenological constraints on broken supersymmetry

We show that the existence of massless color octet quarks, which appear in a class of broken supersymmetric field theories, implies the existence of additional light (? 1 GeV) unstable hadrons with large $\text{(? 10 μb)}$ production cross sections. We estimate the half-life for these states to be less than 10^?8 s. If it is greater than 10^°10 s, these states are already ruled out experimentally.
