| 12 | | The search for new physics (NP) requires novel strategies. NP can still be energetically accessible at the LHC but difficult to detect. In this respect, long-lived particles are interesting possibilities that call for new search methods. For instance, new models put forward by members of the consortium need a strong collaboration with experimentalists to resolve detector issues in the corresponding searches (tracker, as well as jet reconstruction). The connection of these non-conventional particles to dark matter (DM) should also be looked at in a new light. Through the DM connection, this topic straddles all three WPs.\\ |

| | 22 | The discovery of gravitational waves (GW) was one of the major milestones achieved during Enigmass1, opening up a rich science program initiated with the results obtained from the binary black hole and binary neutron star mergers detected so far by LIGO and Virgo. The binary neutron star merger GW170817 was also a spectacular and ground-breaking multi-messenger event, with its short gamma ray burst and kilonova counterparts. Multi-wavelength and multi-messenger observations are key tools to characterize GW sources, the high-energy sky, and cosmic rays, in order to address major open questions in fundamental physics, astrophysics and cosmology. Through remarkable synergies, the consortium is in a unique position to have a high-impact contribution in this line of research within Enigmass2, through experimental and theoretical activities, including strong involvement in several ESFRI projects.|| \\ |

| | 30 | One of the prominent problems of modern physics is the existence of the so-called dark matter. This essential component of the Universe is still of unknown nature. It cannot be made of ordinary atoms, yet it pervades galaxies and clusters. Its presence on cosmological scales has been confirmed by the Planck mission, a project in which Enigmass1 was deeply involved. Planck results are also consistent with a Universe dominated by dark energy, a fluid whose negative pressure is driving a re-acceleration of the expansion. The seeds at the origin of galaxies and clusters of galaxies have presumably been processed during a primordial phase of inflation. Understanding the nature of DM is one of the goals of the consortium, tackled using four different approaches.||\\ |
