description: Multi jet observables are a powerful tool to new physics as well as a boost to standard  analysis strategies. We show their use in a reasonably model independent dark matter  search and a jet veto Higgs analysis. We find however that, these observables are  plagued by huge theoretical uncertainties connected to unphysical scale parameters.  In the democratic limit we compute analytically the all order resummed jet spectrum  at leading log. It obeys so called staircase scaling. With the help of state of the art  Monte Carlo tools we study the jet spectrum features in great detail. In addition we  also study so called Poisson scaling. This allows us to develop a data driven strategy  to fix the standard model multi jet backgrounds.
