Dark matter interpretations of ATLAS searches for the electroweak production of supersymmetric particles in √s = 8 TeV proton-proton collisions Aaboud, M. Aguilar Saavedra, Juan Antonio Atlas Collaboration, / Hadron-Hadron scattering (experiments) A selection of searches by the ATLAS experiment at the LHC for the electroweak production of SUSY particles are used to study their impact on the constraints on dark matter candidates. The searches use 20 fb−1 of proton-proton collision data at √s = 8 TeV. A likelihood-driven scan of a five-dimensional effective model focusing on the gaugino-higgsino and Higgs sector of the phenomenological minimal supersymmetric Standard Model is performed. This scan uses data from direct dark matter detection experiments, the relic dark matter density and precision flavour physics results. Further constraints from the ATLAS Higgs mass measurement and SUSY searches at LEP are also applied. A subset of models selected from this scan are used to assess the impact of the selected ATLAS searches in this five-dimensional parameter space. These ATLAS searches substantially impact those models for which the mass m(χ01) of the lightest neutralino is less than 65 GeV, excluding 86% of such models. The searches have limited impact on models with larger m(χ01) due to either heavy electroweakinos or compressed mass spectra where the mass splittings between the produced particles and the lightest supersymmetric particle is small. 2024-10-16T08:00:40Z 2024-10-16T08:00:40Z 2016-09-30 journal article The ATLAS collaboration., Aaboud, M., Aad, G. et al.
