A search for muon neutrinos originating from dark matter annihilations in the Sun is performed using the data recorded by the ANTARES neutrino telescope from 2007 to 2012. In order to obtain the best possible sensitivities to dark matter signals, an optimisation of the event selection criteria is performed taking into account the background of atmospheric muons, atmospheric neutrinos and the energy spectra of the expected neutrino signals. No significant excess over the background is observed and 90% C.L. upper limits on the neutrino flux, the spin-dependent and spin-independent WIMP-nucleon cross-sections are derived for WIMP masses ranging from 50 GeV to 5 TeV for the annihilation channels WIMP + WIMP -\textgreater b (b) over bar, W+W- and tau(+)tau(-).

Improved limits on dark matter annihilation in the Sun with the 79-string IceCube detector and implications for supersymmetry (2016, methodology): “Indirect DM searches by Antares [36] and Baksan [37] have set less stringent limits on the spin-dependent DM-proton scattering and are consequently not included in Fig.”
