Abstract

Jets plus missing transverse energy is one of the main search channels for new physics at the LHC. A major limitation lies in our understanding of QCD backgrounds. Using jet merging, we can describe the number of jets in typical background channels in terms of a staircase scaling, including theory uncertainties. The scaling parameter depends on the particles in the final state and on cuts applied. Measuring the staircase scaling will allow us to also predict the effective mass for standard model backgrounds. Based on both observables, we propose an analysis strategy avoiding model-specific cuts, which returns information about the color charge and the mass scale of the underlying new physics.
