Abstract: We investigate a minimum set, MSSM with 9 free parameters (p9MSSM) that allows a global study of neutralino dark matter and collider signatures with several constraints. We include measurement of the relic density from PLANCK, the discovery of the Higgs boson, LHC direct SUSY searches, recent evidence for a Standard Model-like Bs mu+mu-, and the measurement of g-2, plus a number of other electroweak and flavor physics constraints.
Two LHC direct SUSY searches at \sqrt{s} = 8 TeV are considered: the CMS inclusive αT search for squarks and gluinos, and miss the CMS electroweak production search with 3 leptons + missing E_T in the final state. Our result shows a neutralino mass in the window 200 GeV Finally, we present prospects for various indirect searches of dark matter, namely \gamma-ray fluxes from dSphs and the Galactic Center at Fermi-LAT, and for positron flux at AMS02. We also show the 5-year sensitivity on the spin-dependent neutralino-proton cross section from neutrino fluxes from the Sun at IceCube. This talk is mainly based on paper Phys.Rev. D88 (2013) 055012 (arXiv:1306.1567).
