Searching for physics beyond the standard model using beta decay — •Marcus Beck — Institut für Physik, Johannes Gutenberg-Universität Mainz
The standard model of particle physics is a well extablished theory. However, it is believed a more general theory with less free parameters exists. This should lead to experimental deviations from the predictions of the Standard Model at some level. One possibility to determine the free parameters of the Standard Model and to search for new physics are precision experiments with beta decay using modern technologies. This will be illustrated with several examples. These include the determination of the first element of the quark mixing matrix, Vud, the determination of the weak coupling constants gA and gV, searches for exotic interactions and the determination of the mass of the electron antineutrino. The latter will be discussed on the basis of the KATRIN experiment in greater detail.
