abstract = {The latest years have seen steady progresses in WIMP dark
matter (DM) searches, with hints of possible signals
suggested by both direct and indirect detection experiments.
Antiprotons can play a key role validating those
interpretations since they are copiously produced by WIMP
annihilations in the Galactic halo, and the secondary
antiproton background produced by Cosmic Ray (CR)
interactions is predicted with fair accuracy and matches the
observed spectrum very well. Using the publicly available
numerical DRAGON code, we reconsider antiprotons as a tool
to constrain DM models discussing its power and limitations.
We provide updated constraints on a wide class of
annihilating DM models by comparing our predictions against
the most up-to-date ap measurements, taking also into
account the latest spectral information on the p, He and
other CR nuclei fluxes. Doing that, we probe carefully the
uncertainties associated to both secondary and DM originated
antiprotons, by using a variety of distinctively different
assumptions for the propagation of CRs and for the DM
distribution in the Galaxy. We find that the impact of the
astrophysical uncertainties on constraining the DM
properties can be much stronger, up to a factor of ~50, than
the one due to uncertainties on the DM distribution (~2-6).
Remarkably, even reducing the uncertainties on the
propagation parameters derived by local observables,
non-local effects can still change DM model constraints even
by $50\%.$ Nevertheless, current ap data place tight
constraints on DM models, excluding some of those suggested
in connection with indirect and direct searches. Finally we
discuss the power of upcoming CR spectral data from the
AMS-02 observatory to drastically reduce the uncertainties
discussed in this paper and estimate the expected
sensitivity of this instrument to some sets of DM models.},
