Prospects for Dark Matter Searches with Measurements of the Electron Flux with GLAST

We discuss prospects for the LAT detection of signatures from the lightest Kaluza-Klein (LKP) particle of universal extra dimensions. The LKP annihilates directly into e+e- pairs and into other channels that produce energetic e+e-, that may be detectable in the high energy electron flux. We discuss the LAT capability to detect high energy (20 GeV-~1 TeV) cosmic ray electrons and protons and analyze the LAT sensitivity to LKP-produced electrons and positrons for various particle masses and pair annihilation cross sections rates, including the effect of electrons diffusive propagation in the galaxy.
