AstroFit: A complementarity interface program for exploring physics beyond the Standard Model, in particular Dark Matter (DM) models. — Nelly Nguyen, •Faruk Alexander Sellami, Torsten Bringmann, and Dieter Horns — University of Hamburg

The AstroFit project aims at combining constraints on the parameter space of DM models, providing an interface between theoretical predictions and results from collider, direct and indirect DM searches. AstroFit is a user-friendly, model-independent, easily expandable interface program that compares experimental data - such as the relic density of DM, photon flux upper limits from dwarf spheroidal galaxies and direct WIMP-nucleus cross-sections - with predictions from theory, currently by using the DarkSUSY program package. Combining AstroFit with fit programs such as Fittino includes these contributions in a parameter model fit of, e.g., supersymmetric parameters to particle physics data. Further inclusions of DM signals, such as antiproton and positron fluxes from indirect searches, are planned for the near future. Here, we will exemplify the functuality of AstroFit, show first results from a fit with AstroFit and Fittino constraining the parameters of a CMSSM model, and illustrate the ideas for next steps with AstroFit.
