Searches for SUSY in hadronic final states at CMS

We present results of searches for SUSY production at CMS in events containing hadronic jets and missing energy, with or without isolated photons or heavy flavor. Various discriminants based on the event kinematics are employed to suppress standard-model backgrounds. The results are interpreted in the context of the Constrained Minimal Supersymmetric Standard Model, and of a number of "simplified models".
