Description
New electroweak states appear in generic extensions of the Standard Model but are challenging to discover at hadron colliders. When the lightest state in a new electroweak multiplet is neutral and all multiplet components are approximately degenerate, production of the charged components is followed by decay into nearly invisible states. If this decay occurs promptly, the only way to infer the presence of the reaction is through its missing energy signature. We propose using emission of photon radiation from these charged states as a means of discriminating the signal from SM backgrounds. We demonstrate the broad applicability of our technique by studying the cases of Higgsinos in natural supersymmetry and quintuplet fields.
