Description

To date the neutrino telescopes IceCube and ANTARES have been generating strong limits on the thermally averaged annihilation cross-secttion of WIMP dark matter in the galactic center, with ANTARES yeilding the currently strongest limits at WIMP masses exceeding 30 TeV. At a WIMP mass range of 50 GeV to a few hundred GeV the current limitss from IceCube surpass those of ANTARES offering a good opportunity for a combined analysis. In this presentation the results of a first combined search for dark matter in the galactic center using the data of both these experiments is presented. As a first step to a combined analysis using both detectors full datasets the 79-string data sample taken from 2012 to 2014 was used from IceCube, while from ANTARES the data sample collected from 2007 to 2015 was taken. The analysis considered dark matter with particle masses between 50 and 100 GeV and a variety of different dark matter halo models and annihilation channels.
