Active projects
Complementarity of dark matter searches in simplified models
Chiara Arina, Fabio Maltoni

Study of the complementarity between dark matter relic abundance, direct detection, indirect detection and collider searches applied to the dark matter simplified models. These models consider a dark matter candidate communicating to the quark (especially top) sector of the standard model via a bosonic or vectorial mediator.

Dark matter and neutrino masses in SUSY models
Chiara Arina, Michele Lucente

We study supersymmetric models in which modifications of the neutrino sector, to include a mass term, are connected to the dark matter sector. We analyse if the dark matter particles can be good dark matter candidates by considering cosmological and astrophysical constraints, as well as if the new neutrino sector can accommodate neutrino data.

External collaborators: Suchitat Kulkarni (OAW Wien).
New Paths to Hidden Sectors
Chiara Arina, Marco Drewes, Andrea Giammanco

We study the perspectives to search for new long lived particles with existing accelerator facilities. This includes searches for non-standard signatures at the LHC main detectors, fixed target experiments and searches in heavy ion collisions.
SUSY phenomenology at LHC
Chiara Arina

Study of the supersymmetric phenomenology at LHC connected to the leptonic experimental searches to go beyond the simplified model spectra approach.

External collaborators: Michael Chala (Desy), Victor Martin Lozano (IFT Madrid), Germano Nardini (ITP Bern).
