Measurement of the beta-asymmetry parameter of Cu-67 in search for tensor-type currents in the weak interaction
Original language description
Precision measurements at low energy search for physics beyond the standard model in a way complementary to searches for new particles at colliders. In the weak sector the most general beta-decay Hamiltonian contains, besides vector and axial-vector terms, also scalar, tensor, and pseudoscalar terms. Current limits on the scalar and tensor coupling constants from neutron and nuclear beta decay are on the level of several percent. The obtained limits are comparable to limits from other correlation measurements in nuclear beta decay and contribute to further constraining tensor coupling constants.
