DESCRIPTION:Using 43 months of public Fermi LAT data\, we find in regions 
 close to the Galactic center a 4.6 sigma excess that is not inconsistent w
 ith a gamma-ray line from dark matter annihilation at around 130 GeV. When
  taking into account the look-elsewhere effect the significance of the obs
 erved signature is 3.3 sigma. If interpreted in terms of dark matter parti
 cles annihilating into a photon pair\, the observations imply a partial an
 nihilation cross-section of about  ~ 10^-27 cm^3 s^-1. I will discuss deta
 ils of the statistical analysis\, caveats\, interpretations and future pro
 spects.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=187081
