Current Work

Our research is focused on testing the boundaries of the Standard Model of particle physics and on looking for new phenomena which might explain unanswered puzzles in the fundamental description of the Universe. The examples of such puzzles would be dark matter nature, matter-antimatter asymmetry of the Universe or very small but non-zero neutrino masses.

The main instrument for these tasks is the LHCb detector at CERN, where the analyses of the data collected in the LHC proton-proton collisions are ongoing. We are also conducting searches for heavy neutral leptons with the CMS experiment at CERN in the context of the ERC Starting grant "MajorNet", ID 758316. At the same time, the R&D activities for future facilities and experiments which exploit complementary strategies are taking place. In particular, we contribute to the operation of the SND@LHC detector, to the R&D for the fixed target program with the SHiP detector to be built at the CERN beam-dump facility at the SPS, and to the R&D for the Future Circular Collider at CERN.
