Andrew Cheek (EOS) (member since October 2019)
My research has focused predominantly on the phenomenology of particle dark matter (DM). Incorporating multiple experimental techniques and looking for novel measurements that could help differentiate between particle models. I have developed RAPIDD, a software to quickly and accurately approximates direct detection of dark matter. I am interested in combining solutions to the dark matter problem with other outstanding problems with the Standard Model.
Research directions:
Cosmology and General Relativity
Phenomenology of elementary particles

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

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).
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).
