Fundamental interactions

Oral

Precision measurements in nuclear beta decay provide sensitive means to test the foundations and symmetries of the standard electroweak model and allow also the determination of fundamental couplings in processes involving the lightest quarks. The main aim of such measurements is to find deviations from the standard model predictions as possible indications of new physics. These indirect...

Oral

Low energy precision experiments for the search of exotic components in the weak interaction are complementary to the high energy experiments at the colliders dedicated to discover new particles. In the case of the WITCH experiment the beta neutrino angular correlation coefficient (a) in nuclear beta decay is studied. A deviation from the distribution predicted by the standard model will...

Fundamental interactions

Oral

The precise measurement of the beta-neutrino angular correlation coefficient "a" in nuclear beta decay is a sensitive tool to search for exotic couplings presently excluded by the V-A theory of the weak interaction. For instance, the study of a pure Gamow-Teller (GT) transition enables to probe tensor-type couplings while a pure Fermi (F) transition is sensitive to scalar-type interactions....
