SloopS: a code for one-loop processes in the MSSM with applications to Collider Physics and Dark Matter TO EDIT The long awaited LHC will be launched in a few months. The LHC research program has traditionally centred around the discovery of the Higgs. However, the standard model description of this particle calls for New Physics. Until a few years ago the epitome of this New Physics has been supersymmetry which when endowed with a discrete symmetry furnishes a good Dark Matter, DM, candidate. Recently a few alternatives have been put forward. Originally this was to solve the Higgs problem but it has been discovered that, generically, their most viable implementation (in accord with electroweak precision data, proton decay,..) fares far better if a discrete symmetry is embedded. This symmetry is also behind the existence of a possible DM candidate. From another viewpoint, the last few years have witnessed spectacular advances in cosmology and astrophysics confirming that ordinary matter is a minute part of what constitutes the Universe at large. At the same time as the LHC will be gathering data, a host of non collider experiments will be carried out in search of DM (PLANCK, GLAST, AMS, HESS, Edelweiss,..) with an accuracy making cosmology enter the era of precision. The emergence of this new paradigm means it is of utmost importance to analyse and combine data from these upcoming observations with those at the LHC. This will also pave the way to search strategies for the next Linear Collider, ILC. This crucial programme is only possible if a cross-border particle-astroparticle collaboration is set up having at its disposal common or complementary tools to conduct global searches and analyses. Moreover it is crucial to associate theorists and experimentalists from these two communities. Our proposal is to develop, improve, interface and exploit such tools for the prediction and analysis of Dark Matter signals from a combination of terrestrial and non terrestrial observations, paying due attention to astrophysical uncertainties. |

The context
This year will see the
launch of the much awaited Large Hadron Collider, LHC. The main raison d'être
of this major international project has been the elucidation of the mechanism
of symmetry breaking and the concomitant problem of the mass of all elementary
particles through the search of the elusive Higgs particle. The Higgs is the
missing link in the much successful Standard Model, SM, description of high
energy physics. In fact, when it comes to the sector of symmetry breaking,
there are numerous theoretical arguments that hint to New Physics so that we
expect a wealth of new data at the LHC. Apart from various theoretical
arguments, most recent observations like the celebrated WMAP (Wilkinson Microwave Anisotropy Probe) have confirmed that
ordinary matter accounts for a minute portion of what constitutes the Universe
at large. There is an overwhelming dominance of Dark Energy and Dark Matter, DM.
This, in itself, is New Physics. Add to this that the majority of models for
the New Physics whose primary aim is a better description of the Higgs sector
of the SM provide as a bonus a candidate
for DM, it is fair to say that we are witnessing the emergence of a strong
cross breeding between high energy collider physics on the one hand and
cosmology and astrophysics on the other to unravel the mystery of DM. It is
also important to stress that at about the same time as the LHC will be
gathering data, other significant experiments (PLANCK, GLAST, AMS, HESS, CDMS,
Edelweiss,...) will have provided or will be providing unprecedented information
on DM and hence on the New Physics. It
is therefore of utmost importance to get ready for the analyses and combination
of the wealth of data from these
upcoming non-collider observations with those at the LHC. This will also pave
the way to search strategies for a future international e+e-
Linear Collider, ILC. This important
programme is only possible if a cross-border particle-astroparticle
collaboration is set up, having at its disposal common or complementary tools
to conduct global combined analyses. Moreover it is crucial to associate
theorists and experimentalists from these two communities for such a project.
