Description

Precision measurements in nuclear beta decays are sensitive probes to test the foundations and symmetries of the Standard electroweak Model and to search for exotic couplings presently excluded by the V-A theory in processes involving the lightest quarks. The main aim of such measurements is to highlight deviations from the Standard Model predictions as possible indications of new physics, complementing high energy physics experiments. The sensitive parameters are often deduced from correlation studies between the very few bodies involved in the decay or from the shape of event distributions. This requires to perform very precise measurements using advanced technical methods installed on-line in radioactive nuclei production facilities. Data analysis also requires generating the most realistic simulations to take into account the relevant parameters of the experimental setup and their systematic effects on the measured quantities.
In this presentation, I will highlight some key experiments in which LPC Caen is involved and I will discuss perspectives, especially considered in the DESIR facility at GANIL.
