Abstract
Dark matter (DM) particle annihilation or decay can produce monochromatic -rays readily distinguishable from astrophysical sources. -ray line limits from 30 GeV to 200 GeV obtained from 11 months of Fermi Large Area Space Telescope data from 20-300 GeV are presented using a selection based on requirements for a -ray line analysis, and integrated over most of the sky. We obtain -ray line flux upper limits in the range , and give corresponding DM annihilation cross-section and decay lifetime limits. Theoretical implications are briefly discussed.
