LHC Dark Matter WG public meeting

Monday 18 Dec 2017, 09:00 → 19:10 Europe/Zurich

40/S2-D01 - Salle Dirac (CERN)

Antonio Boveia (CERN), Caterina Doglioni (Lund University (SE)), Michelangelo Mangano (CERN), Oliver Buchmueller (Imperial College Sci., Tech. & Med. (GB)), Philip Coleman Harris (Massachusetts Inst. of Technology (US)), Tim Tait (University of California, Irvine), Ulrich Andreas Haisch (University of Oxford (GB))

Discussion meeting of the LHC Dark Matter Working Group, focused on:

1) Conclusion of the work on scalar and pseudoscalar models (2HDM) and on the t-channel models

2) Overview and critical comparison of ATLAS and CMS DM results with 2015+2016 data

3) New ideas for future directions, including but not limited to:

• connections between existing models and dark sector models
• HL-LHC and HE-LHC prospects for dark matter searches
• upcoming improvements to precision calculations and tools for DM searches
• further refinement to current benchmark models towards new signatures 
• presentation of joint ATLAS and CMS results (summary plots)
