As we have argued repeatedly in this proposal, the microscopic properties of DM will most unambiguously be probed through precision analyses at the colliders, hence the need for accurate simulation tools and ``fitters" for the extraction of the underlying parameters. If these are measured precisely, important constraints on both the cosmology and the astrophysics of DM will be made. To this end one needs to measure not only the mass but a set of couplings from a large set of well chosen observables. It may well be, that unless one makes strong guesses on the model, the LHC will only be able to furnish a few, though important, hints or measurements leaving a more refined analysis for the ILC, provided the latter has enough energy.  We are lucky to have in our project a team of experimental particle physicists, from the LHC and the ILC, which has the expertise in event generators and tools like SFitter that will be interfaced to the cross sections provided by micrOMEGAs  so that we are in a position to conduct the kind of global analyses.

Apart from the development of SFitter and the UED event generator developed for ATLAS by the members of our project[8], some of the avenues pursued by the team, in conjunction with the project, is to investigate, within different models of New Physics,  new sets of observables beside some golden channels (like the dileptons in the case of supersymmetry at the LHC) that are conducive to a useful extraction of parameters. For example, a preliminary investigation indicates that within some manifestation of supersymmetry, some cascade decays of the neutralino may yield the sign of the µ parameter.  Precision investigation of the Higgs may also yield information on DM. An invisible Higgs may be an indication of decays into the DM candidate[29]. Much needs to be done to determine  the best observables especially  for non supersymmetric models, although some preliminary studies have been made for UED in the ATLAS environment in view of disentangling between models[8].

With the one-loop cross sections that SloopS will provide, there are some exciting precision analyses to be made in the context of the LHC and ILC for the microscopic properties of DM.  Moreover the development of more sophisticated event generators, incorporating polarisation effects and beamsstrahlung, can be exploited to optimise the detector design for the best signal efficiency and the lowest background.

Detailed studies of the collider phenomenology of DM candidates from New Physics, model determination and parameter extraction, are very involved and require a full-time occupation. We hence request a post-doc for this topic. The post-doc  (18 months) will be working at LPSC in Grenoble under the guidance of S. Kraml and M. Klasen. She or he will also, naturally, have strong links with the LAPP (SFitter group) and LAPTH theorists.
