DESCRIPTION:Speakers: Dr. SERPICO\, Pasquale Dario (Fermilab)\nWe discuss 
 the general observational upper limits on the total annihilation rate of\n
 dark matter derived from the diffuse gamma ray background measured by the 
 EGRET\nsatellitr. We assume that the dark matter annihilates at tree level
  in the least\ndetectable final states in the Standard Model\, namely neut
 rinos. Any other decay\nchannel would lead to stronger constraints. Electr
 oweak jet cascading imply that\, for\nmasses above ~100 GeV\, interesting 
 bounds apply which are much more stringent than\nwell-known general bounds
  as the unitarity one and comparable or only a few times\nweaker than the 
 bounds recently derived from atmospheric neutrino data.\nWe briefly discus
 s the perspectives of improvement of these constraints on the light\nof fo
 rthcoming GLAST stellite data.\n\nhttps://indico.nucleares.unam.mx/event/4
