  1. MadDM 0 . 2 . V Dark Matter Phenomenology in the MG5_aMC@NLO framework Gopolang (Gopi) Mohlabeng with Mihailo Backovic, K.C. Kong, Antony Martini and Olivier Mattelaer arXiv:1505.04190

  2. BSM Physics in LHC era Standard Model has been very successful in explaining - observed particle physics phenomena. Some deficiencies: ★ Baryogenesis. ★ Leptogenesis. ★ Neutrino Masses. ★ Dark Matter. ★ Dark Energy. DM is very well motivated for New Physics beyond SM. - Why? Many intriguing and undeniable hints that DM exists

  3. DARK MATTER Evidence From Astrophysics and Cosmology Rotational velocities of spiral galaxies Bullet Cluster van Albada et al 1985 Unobservable Matter home.slac.stanford.edu available:10/30/14 Gravitational Lens Gravitational Lensing Velocity dispersions, CMB maps, N-body simulations CMB map Millenium Simulation en.wikipedia.org [available:10/30/14] www.mpa-garching.mpg.de

  4. Dark Matter Complementarity We have no sense of where new physics is hiding - DM models alone span many orders of magnitude in energy scales http://home.physics.ucla.edu/~arisaka/home/Dark_Matter/ Complementarity studies require powerful simulation tools

  7. MadDM MadDM emerged as an e ff ort to link: 
 - DM collider searches , with 
 - early cosmology signatures (relic density) and 
 - direct/indirect detection . Goal is to allow both Experimentalists and Theorists to calculate signatures of DM models at all interfaces with click of a button. User friendly architecture of MadGraph_aMC@NLO provides ideal framework for MadDM development.

  8. MadDM MadDM emerged as an e ff ort to link: 
 - DM collider searches , with 
 - early cosmology signatures (relic density) and 
 - direct/indirect detection . Version 1.0 of MadDM focused on calculations of 
 DM relic density (in a generic UFO model). Version 2.0 of MadDM extends the functionality to 
 DM direct detection.

  9. Testing of model points MadDM v.2.0 also incorporates a simplified model testing functionality : The user can compare the results to existing constraints 
 (relic density, direct detection cross section etc.) Example output: The ultimate goal is to confront DM models with collider, astro physical and cosmological constraints in a fully automated framework!

  10. i.e. we would like to have Collider bounds together with Astrophysical and Cosmological signatures. MadDM has already been used by the CMS experiment, - in the search for DM EFT’s in Mono-jet/Z analyses Relic Density using MadDM -1 19.7 fb (8 TeV) µ (GeV) up CMS Preliminary g =g =1 DM q DM 2 2 200 m Scalar Median Expected ( µ =1) up Observed +/- Scale Uncertainty 1.5 1.5 Median Expected (Fermion only) Observed (Fermion only) LUX Planck+WMAP Relic 1 1 100 0.5 0.5 0 0 50 100 150 200 250 300 350 400 m (GeV) med CMS collaboration 2015: CMS-PAS-EXO-12-054 CMS collaboration 2015: CMS-PAS-EXO-12-055

  11. MadDM Status In Progress Model testing Database of Link to Pythia/ experimental GALPROP results (e.g. HiggsBounds) Still discussing… MadDM NLO Finished Urgent! Direct detection Integration with MG5_aMC@NLO Indirect detection Directional detection Finished Web interface Urgent!
