The Dirac equation predicts the muon gyromagnetic ratio g=2. Loop effects from quantum field theory lead to a small deviation from this value, parameterized by the so called anomalous magnetic moment which is defined as aμ=(g-2)/2. The difference…

Nuclear quadrupole moments (Q), a measure of charge asymmetry in nuclei, are experimentally accessible via the quadrupole interaction frequency νQ=eQVzz/h. To extract Q from this information one needs to knowVzz, the electric-field gradient at the…

Gravitational waves contain crucial information on the structure and on the history of the Universe. They can give us access to unique insights on particle physics at very high energies and astrophysics in extreme regimes. The detection of…

The ATLAS experiment is a general-purpose particle detector operating at the LHC. It consists of several concentric layers of particle detectors occupying a cylindrical volume 46m long and 25m in diameter. The innermost detectors reconstruct the…

Quantum Chromodynamics (QCD), the theory of strong interactions, is characterised by a rich phase diagram. The elementary coloured degrees of freedom of the theory, quarks and gluons, under ordinary conditions are confined in colour-neutral hadrons…
