Search for dark matter towards the Galactic Centre with 11 years of ANTARES data Albert, A. López Coto, Daniel Navas Concha, Sergio Díaz, A. F. Dark matter indirect detection Neutrino telescope Galactic Centre ANTARES Neutrino detectors participate in the indirect search for the fundamental constituents of dark matter (DM) in form of weakly interacting massive particles (WIMPs). In WIMP scenarios, candidate DM particles can pair-annihilate into Standard Model products, yielding considerable fluxes of high-energy neutrinos. A detector like ANTARES, located in the Northern Hemisphere, is able to perform a complementary search looking towards the Galactic Centre, where a high density of dark matter is thought to accumulate. Both this directional information and the spectral features of annihilating DM pairs are entered into an unbinned likelihood method to scan the data set in search for DM-like signals in ANTARES data. Results obtained upon unblinding 3170 days of data reconstructed with updated methods are presented, which provides a larger, and more accurate, data set than a previously published result using 2101 days. A non-observation of dark matter is converted into limits on the velocity-averaged cross section for WIMP pair annihilation. 2020-07-29T11:50:30Z 2020-07-29T11:50:30Z 2020-04 info:eu-repo/semantics/article Albert, A., André, M., Anghinolfi, M., Anton, G., Ardid, M., Aubert, J.
