Dark ma'er what is it and how well can one determine its - PowerPoint PPT Presentation

Dark ma'er – what is it and how well can one determine its proper5es? Leszek Roszkowski BayesFITS Group Na5onal Centre for Nuclear Research (NCBJ), Warsaw, Poland and University of Sheffield, UK Ø Dark ma'er is made up of WIMPs Ø DM WIMP is part of some ``new physics” beyond the SM L. Roszkowski, PTF, Katowice, 14/05/2016 1

Where is ``new physics”? Ø No convincing hint from the LHC but… Higgs boson: Ø Fundamental scalar --> SUSY Ø Light and SM-like --> SUSY Low energy SUSY remains the front-runner for ``new physics” L. Roszkowski, PTF, Katowice, 14/05/2016 2

Plan: ² Implica5ons of Higgs boson m h ~125 GeV and direct limits on SUSY: DM WIMP: ~1 TeV (higgsino) ² Prospects for detec5on in unified and general SUSY models ² complementarity of LHC and DM searches (direct and CTA) ² Once WIMP detected: challenge of WIMP reconstruc5on ² Summary Based mainly on: • K.
