The LHC Run I (2010-2012) has been tremendously successful with the discovery of a Higgs boson at 125 GeV by the ATLAS and CMS experiments.
Beyond the Higgs particle the large LHC experiments were designed to probe TeV scale physics and a wide range of theoretical models.
One of the theories hailed as a possible successor for the established Standard Model is Supersymmetry which can provide
a dark matter candidate and could solve a number of conceptual problems. From an experimentalist point of view supersymmetry also provides
a template for new-physics signals that spans over many experimental signatures. A systematic search for supersymmetry effectively provides
a nearly exhaustive exploration of experimental signatures.
The supersymmetric partners of the electroweak gauge bosons are the so-called weak gauginos, the lightest of which could make up the Dark Matter.
Production of these weak gauginos could be the dominant signal from new physics at LHC. The latest results of search for weak gaugino production
with the full Run I ATLAS data are presented. The limitations of the current results are discussed together with possible way forwards based on
innovative experimental signatures.
