Indirect Detection Analysis: Wino Dark Matter Case Study
  We perform a multichannel analysis of the indirect signals for the Wino Dark
Matter, including one-loop electroweak and Sommerfeld enhancement corrections.
We derive limits from cosmic ray antiprotons and positrons, from continuum
galactic and extragalactic diffuse gamma-ray spectra, from the absence of
gamma-ray line features at the galactic center above 500 GeV in energy, from
gamma-rays toward nearby dwarf spheroidal galaxies and galaxy clusters, and
from CMB power-spectra. Additionally, we show the future prospects for neutrino
observations toward the inner Galaxy and from antideuteron searches. For each
of these indirect detection probes we include and discuss the relevance of the
most important astrophysical uncertainties that can impact the strength of the
derived limits. We find that the Wino as a dark matter candidate is excluded in
the mass range bellow ~800 GeV from antiprotons and between 1.8 and 3.5 TeV
from the absence of a gamma-ray line feature toward the galactic center. Limits
from other indirect detection probes confirm the main bulk of the excluded mass
ranges.
