Seminarium "Teoria cząstek elementarnych i kosmologia"

We are entering an era of high-precision neutrino oscillation experiments (T2HK, DUNE), which potentially hold answers to some of the most exciting questions in particle physics. Their scientific program requires a precise knowledge of neutrino-nucleus interactions coming from fundamental nuclear studies. Ab-initio many-body theory has made great advances in the last years and is able to give relevant predictions for medium-mass nuclei important for neutrino experiments. In my talk I will give an overview of the recent progress that has been made in describing electroweak nuclear processes within the ab-initio coupled-cluster framework. These techniques open the door to obtaining nuclear responses (and consequently cross-sections) for medium-mass nuclei starting from first principles.
