Description
Physics beyond the Standard Model (SM) is required to understand many unexplained features, both of particle physics and of cosmology. Precision measurements in neutron beta decay allow searching for physics beyond the SM.
The PERKEO III collaboration performed a measurement of the proton asymmetry C, which describes the angular correlation between the momentum of the decay proton and the spin of the neutron. In the SM, neutron decay is covered within the framework of V-A theory. All asymmetry parameters depend only on the ratio of axial-vector coupling constant (gA) over vector coupling constant (gV).
We will present preliminary results of the last measurement period.
