Physics

• Study of the fundamental interactions by means of

- proton-proton scattering at the LHC collider (CMS experiment, in data-taking);

- electron-proton scattering at the HERA collider active until 2007 hosted by the DESY laboratory in Hamburg (ZEUS experiment, data still under analysis);

- electron-proton and electron-io scattering at the future EIC collider hosted by the BNL laboratory in Long Island, NY (EPIC experiment, under design)

The goal is to understand the behaviour of the constituents of matter (quarks and leptons) and to answer some of the open questions in our understanding of the universe, among which the nature of dark matter and the origin of the asymmetry between matter and anti-matter.

• Development of innovative detectors for ionising radiation, with the capability to measure the impact point of the radiation and its arrival time with resolutions of a few microns and a few tens of picoseconds, respectively. These are silicon sensors that can be used in high-energy physics but also in diagnostic/therapeutic as well as industrial applications.
