What are the smallest constituents of matter and what forces act on them? The division participates in the ATLAS and ALICE experiments at the LHC at CERN and contributes to their upgrades. These experiments produce complex data and require e-science methods to handle it. We develop models to describe and explain the observations as well as theories that predict new phenomena not yet observed. Dark Matter is the majority of the matter in the Universe, but what is it made of? The LDMX experiment is being prepared to answer that question. The HIBEAM/NNBAR collaboration is a planned international programme of searches for neutron conversions between matter and antimatter at ESS. Research on the stability and structure of atomic nuclei is conducted within the international FAIR-NUSTAR and CERN-ISOLDE collaborations, but also at other facilities in Europe and the USA. In applied nuclear physics, we study anthropogenic radioactivity in the environment in co-operation with Medical Radiation Physics in Malmö.

The Division of Particle and Nuclear Physics spans broad across subatomic physics and acts largely within international research environments. We conduct experimental and theoretical research with collider experiments. We are engaged in dark-matter searches, fundamental physics with neutrons, nuclear structure and nuclear reactions at the limits of nuclear stability, as well as studying man-made radioactivity in the environment. Theory activities include standard model and beyond, phenomenology, and more. Have a look at the research units' pages on the official website https://particle-nuclear.lu.se for more details!
