Various types of particles are essential ingredients for nuclear medicine applications. Nuclear medicine imaging procedures rely either on gamma-rays or on annihilation photons after positron annihilation, while charged particles with relatively short range are used for therapeutic applications. Targeted radionuclide therapies employing beta or alpha emitters have recently made tremendous progress in the treatment of metastasized cancers.   mehr...

The development of advanced detector technologies is key to the success of nextgeneration high-energy physics experiments, such as at the FCC-ee. In this context, quantum-engineered scintillating materials open new opportunities for innovative detector designs. One such concept is chromatic calorimetry, a novel approach to homogeneous electromagnetic calorimetry that reconciles detector homogeneity with longitudinal segmentation of particle showers.   mehr...

The optical spectrum of atoms and ions offers a unique window into the nucleus, giving access to nuclear properties such as charge radii, spins and nuclear moments that reveal single-particle and collective effects alike. This approach applies equally well to stable and short-lived isotopes.   mehr...

The LHCb experiment at CERN’s Large Hadron Collider is one of the most sensitive instruments for seeking sources of physics beyond the Standard Model. Rare decays of heavy flavour are heavily suppressed in the Standard Model, and new particles can give sizeable contributions to these processes. Their precise study therefore allows for sensitive tests of lepton-flavour universality, as well as detailed measurements of angular observables.   mehr...
