175. Asymmetric WIMP Dark Matter in the presence of DM/anti-DM OscillationsGabrijela Zaharijas, 2012, published scientific conference contribution abstract Abstract: The class of ‘Asymmetric Dark Matter’ scenarios relies on the existence of a primordial
particle/anti-particle asymmetry in the dark sector related to the baryon asymmetry as a
way to address the observed similarity between the baryonic and dark matter energy densities
today. Focusing on this framework we calculate the evolution of the dark matter relic
abundance in the presence of particle/anti-particle oscillations. We show how oscillations reopen
the parameter space of asymmetric dark matter models, in particular in the direction of
allowing large (WIMP-scale) DM masses. Finally, we constrain the parameter space in this
framework by applying up-to-date bounds from indirect detection signals on annihilating DM.
Keywords: dark matter, early universe

179. Galactic Dark Matter signal and the Fermi-LAT measurement of the diffuse gamma-ray emissionGabrijela Zaharijas, published scientific conference contribution Abstract: We study diffuse gamma-ray emission at intermediate Galactic latitudes measured by the Fermi LAT with the aim of searching for a signal from dark matter annihilation or decay. In the absence of a robust dark matter signal, constraints are presented. We present and improve upon conservative dark matter limits obtained with no modeling of the foreground astrophysical diffuse emission. We do so, by taking into account uncertainties in several parameters which characterize conventional astrophysical emission and using a profile likelihood formalism. The resulting limits impact the range of particle masses over which dark matter thermal production in the early Universe is possible, and challenge the interpretation of the PAMELA/Fermi-LAT cosmic ray anomalies as annihilation of dark matter.
Keywords: Dark matter, high-energy gamma rays
