DESCRIPTION:Speakers: Paolo Panci (Institut d'Astrophysique de Paris (IAP)
 )\nWe reconsider the model of Minimal Dark Matter (a fermionic\, hyperchar
 ge-less quintuplet of the EW interactions) and precisely compute its gamma
  ray signals. We compare them with a number of gamma-ray probes: the galac
 tic halo diffuse measurements\, the galactic center line searches and rece
 nt dwarf galaxies observations. We find that the original minimal model\, 
 whose mass is fixed at 9.4 TeV by the relic abundance requirement\, is par
 ticularly constrained by the line searches: it is ruled out if the Milky W
 ay possesses a cuspy profile such as NFW but it is still allowed if it has
  a cored one. Searches of gamma-ray lines from dwarf spheroidal galaxies a
 re also particularly relevant\, and ongoing astrophysical progresses have 
 the potential to eventually rule out the model. We also explore a wider ma
 ss range. Furthermore\, most of our results can be safely extended to the 
 larger class of multi-TeV WIMP DM annihilating into massive gauge bosons.\
