A general search for new phenomena with the ATLAS detector in pp collisions at √ s = 7TeV

We present results of a Model-Independent General Search for new physics in proton-proton collisions at √ s = 7TeV. Data collected by the ATLAS experiment in 2011, for a total integrated luminosity of 4.7 fb −1 has been used. All event topologies involving isolated electrons, photons, muons, jets, b-jets and missing transverse momentum are subdivided according to their final states into exclusive classes. A search algorithm is then used to scan all classes for deviations from the Monte Carlo simulated background in the distribution of the scalar sum of transverse momenta. No excess over the Standard Model expectation is observed.
