Three teams of scientists from Norway, Czech Republic and Iceland join expertises in the attempt to shed light onto the nature of the most abundant ingredient in the Universe: dark matter.

Astronomers are buzzing with excitement as the Euclid Consortium shares a first look at the cosmos through the eyes of the groundbreaking Euclid telescope. The release of the first scientific publications is a milestone for the entire astrophysical community.

Searching for the nature of Dark Matter combining Astro-, Astroparticle- and Particle Physics.

Do new fundamental forces show up at the LHC the way the Z and Higgs bosons did? According to superstring theories, which propose to unify all fundamental forces, including gravity, there is room for new forces to be mediated by new gauge bosons, known as Z’ and W’. The W’ boson is also predicted by theories aiming at restoring parity (left-right) symmetry at high energies. This work consists of: (i) a detailed study and implementation into MC generators of various theories beyond the SM, (ii) an analysis of ATLAS data, taken at the highest available energies, and a comparison to simulation data. You will make use of one of the following processes:

Symmetries play a crucial role in physics. Supersymmetry (SUSY) relates integer spin particles (bosons) and half-integer spin particles (fermions). It allows unification of the electroweak and strong interactions, proposes dark matter candidates, and predicts five Higgs bosons (3 neutral and 2 charged ones). Processes of interest involve superpartners of the leptons (superpartners have a "~" above the particle), of the gauge and Higgs boson(s), as well as a dark matter particle, which is predicted to be the lightest supersymmetric particle (LSP).
