The LAT Dark Matter and New Physics Working group has been developing approaches for the indirect detection of in situ annihilation of dark matter. Our work has assumed that a significant component of dark matter is a new type of Weakly Interacting Massive Particle (WIMP). The annihilation of two WIMPS results in the production of a large number of high energy gamma rays (> 1 GeV) that can be well measured in the GLAST LAT. These searches involve strategies for observation of the galactic center, galactic halo (optimized diffuse all sky analysis), galactic satellites (almost point, high latitude, sources), and cosmological signals in the extra-galactic diffuse. The spectra of these potential signals are considerably harder than most, if not all, astrophysical sources, have an endpoint at the mass of the WIMP, and are not power laws. In addition, there is the possibility to observe lines from annihilation into gamma-gamma and/or gamma-Z final states. The estimates of LAT sensitivity depends upon the WIMP model, the DM halo model and other astrophysics backgrounds. Thus estimates of LAT sensitivity can vary over orders of magnitude depending on which models are chosen. Preparations for these searches and other type of new physics searches will be presented.
