Usually three classes of experimental approaches are distinguished in the hunt of the DM particles. Firstly, DM is searched by direct detection experiment, where DM can be revealed by scattering off of a target material in usually underground detectors. Secondly, DM particles might be be produced at colliders and show up as "missing-energy" events. Thirdly, pieces of information may be obtained also from detecting the products of DM annihilation or decay. 

These different classes of experimental strategies are characterized by different capabilities, so that, assuming that a signal will be reported in all types of experiments, they will be able to constraint the DM hypothesis in different ways. The possibility of combining the results from multiple experiments can become useful in order to maximize the amount of information that can be extracted on the nature of the DM particle. I this workshop we invite physicists that have worked on these topics to present their latest results and to highlight which are the potentiality, but also the limit of this combining approach. Moreover, recently, boosted by the results on the spectra of electrons and positrons component of cosmic rays, many DM models have appeared to fit the data provided by the PAMELA, ATIC, HESS and Fermi collaborations. Some of these models can be constrained or even ruled out based on predictions about physical observables other that the electrons’ and positrons’ energy spectra. For example, DM particles annihilating only into e+ e− are strongly constrained by gamma-ray observations due to the amount of photons produced through inverse Compton (on the optical or infra-red light) by the electrons that come from DM annihilation. Again, the simultaneous analysis of different signals (or predictions) coming, e.g., from different particles (multi-messenger) or from different energy ranges (multi-wavelength) results to be very useful in the effort of pinning down the knoweledge of the potential models of DM. 

The possibility of correctly simulating and analyzing results from topics that are so different, suggests that such goal may be better achieved if different people join together, sharing their expertise. The goal of this workshop is, exactly, that of gathering people that are interested in this possibility, knowing that the question of how to combine different results will be a crucial one, in the hypothesis that many experiments will start in the future to report new detections.

We organize a 5-days workshop with the title “Multi Cube: a multi-wavelength, multi-messenger and multi-experiment approach to Dark Matter searches .
Our intention is to invite speakers instead than having a public opening for contributions. This is motivated by our desire to reach a maximum of 30 participants in order to keep the workshop “informal” and to ease the discussion. The main topic of Multi^3 will be the possibility of combining different experimental approaches and techniques in the search of DM in order to maximize the information.
