We intend to study different photon-isolation prescriptions (standard and smooth cone), extending previous studies to new hybrid isolation. We would like to recommend the use of the isolation parameters applied by the LHC, without any tuning procedure.We intend to estimate numerically the size of the power corrections associated to the qT-subtraction formalism and the behaviour of such power corrections in function of the isolation parameters.
