Final Report Summary - NEWDARK (New Directions in Dark Matter Phenomenology at the TeV scale) The NewDark project has aimed at exploring new directions in Dark Matter phenomenology, with a multi-disciplinary approach that has its roots in theoretical particle physics and cosmology but constantly looks at astrophysical observations and experimental particle physics results, trying to make the most of the bi-directional interactions. The ultimate goal of this project, of course as a part of a larger global effort, was the identification of the nature of the Dark Matter and the exploration of its full phenomenology. Dark Matter’s true nature has not been discovered yet, so we did not achieve this ultimate optimistic goal. However, in the past 6 years the NewDark team has moved steps towards it and obtained significant results which have had a sizable impact on the scientific community. The work on Indirect Dark Matter Detection has seen the most active developments, with contributions by all team members. The team has published more than 50 research articles on top international journals (plus a similar number of proceedings of conferences, some very prestigious such as the ICRC -International Cosmic Ray Conference) and has had a very relevant impact (quantified for instance by more than 2700 citations so far). We have covered all the signals. We worked extensively on antiprotons, leptons, gamma rays, radio waves and neutrinos as messengers from DM. We have been the first ones (together with a competing group from Germany and California) to consider antinuclei as a signal from DM. We have also worked on alternative hypothesis such as Primordial Black Holes. We have also worked intensively on collider searches for Dark Matter, in collaboration with the ATLAS experiment at CERN, and on Direct Detection, on which also a review has been published. And we have kept strong ties with astrophysicists and cosmologists. An important and lasting output of the project consists in numerical results which are put at the disposal of the community. These concern both Direct and Indirect Detection and they have been used by hundreds of research groups so far. The team has been very actively involved in outreach activities and transfer of knowledge, notably towards the general public and high school teachers (more than 30 recognized activities in 6 years, several of which involving more than one event). Two of the team members have received awards for their work, in France and in Italy.
