Our proposal is to develop, improve, generalise, interface and exploit such common and complementary tools for the prediction and analysis of Dark Matter signals from a combination of terrestrial and non terrestrial observations, paying particular attention to the uncertainties that usually afflict astrophysical calculations and SM backgrounds that pollute New Physics signals.  This requires a know-how in building of codes and complex calculations for cross sections of relevance  at the colliders, both for the SM and the New Physics as well as for Dark Matter annihilation.  For the latter, the ability to convolute with the astrophysical and/or cosmological properties, weighing at every stage the different hypotheses and uncertainties that entail this part of the calculation, is crucial. Last but not least, exploitation of these codes is best evaluated and physics studies best conducted in conjunction with experimentalists versed in simulations and who have developed and interfaced  tailor-made tools  for data analyses.

The proposal is carried by an ongoing collaboration between teams from LAPP, LAPTH, LPSC and IAP that have a proven track record in the different aspects of the project. This is a rare mix. Indeed, the present members from the  two experimental teams at LAPP involved in the project are heavily implicated, on the one hand in collider physics (LHC and ILC) and the other in astrophysics (AMS and HESS). They all have been a driving force in data analysis and simulations (electroweak fits[4], supersymmetry searches at LEP[5], standard model and SUSY event generators for e+e-[6], authors of codes such as SFitter [7] for SUSY fits at the LHC and ILC, codes to study aspects of Universal Extra Dimensions, UED, at the LHC[8]...). 

Part of the theory members of LAPTH teaming with a  young recruit from IAP draw from a recognised astrophysics team heavily involved in indirect signals of Dark Matter with sophisticated codes for the propagation of cosmic ray anti-protons[9] and positrons and studies of gamma rays[10,11]. The impact of clumps and boost factors[12] such as might occur for example with the formation of intermediate mass black holes[13] are also hot topics. There is also interests in unconventional cosmological scenarios of the early universe[2].  The particle physicists of LAPTH are among the few theorists that have conducted some of the most complex calculations in the Standard Model (multi-leg processes at one-loop)[14,15], in supersymmetry[16,17] and the Higgs (two-loop)[18]. They have furnished the popular public code micrOMEGAs[19] for the calculation of the relic density in various models of supersymmetry[19]. Many of these calculation feats would not have been possible were it not for the exploitation of automated codes for the SM[15] and the New Physics[19,20].

 Automation will be an important component of this project. It will help build up a modular structure of codes that easily incorporate New Physics models ``turning their Lagrangian" into simulation codes. Combined with the expertise and the complementarity of the teams we believe that such an ambitious and original project will be brought to fruition if these teams are strengthened. The possibility for our teams to invite other world experts, beside incorporating young post-docs, and to organise small interactive Workshops is a key element of the project and a source of momentum for the collaboration.

Since the emphasis of the project will be on the development and the exploitation of codes and tools, to stress the feasibility of the project it is important to point out that many first-class codes, most of which are now public and widely used, have been developed by the members of the project

•   CRAC: (Cosmic Ray Alpine Code), code for the galactic propagation of antiprotons[9].
•   Grace-Loop: Automatic calculation of multi-leg processes in the electroweak theory[14].
•   MicrOMEGAs:  Code for the dark matter relic density, originally in the context of supersymmetry, that has recently been extended to incorporate a generic model. It is also being developed for applications to direct and indirect detection[13].
• Pythia_UED: a Pythia-based generator tool for Universal Extra-Dimension at the LHC[8].
• SDECAY, SUSY_HIT: Code that computes the decay of supersymmetric particles[16].
• SFitter: Code for the reconstruction of the fundamental parameters of supersymmetry from simulations or experimental measurements. Under development to include fits to other model of electroweak symmetry breaking [7].
• SloopS: General code, under development, for one-loop calculations in susy with application to collider data, precise relic density predictions and indirect detection [20,21].
• SusyBSG: a powerful code for bÒs γ in supersymmetry[22].
• SUSY_SCT: a SUSY spectrum comparison tool[23].
