Recent Results of the COBRA Experiment
Original language description
The CdZnTe 0ν Double Beta Research Apparatus (COBRA) is a low background experiment searching for double beta (ββ) decays with CdZnTe (CZT) room temperature semiconductor detectors. The "source = detector" concept of the experiment not only allows the investigation of ββ nuclides naturally present in the detector, but also the study of other rare event processes with high inherent detection efficiency. One process investigated is the fourfold forbidden non-unique single β-decay of113Cd which is measured to evaluate the quenching effects of the axial-vector coupling strength gA, a crucial parameter for the nuclear matrix elements. The other process being focused on is the113Cd charge non-conserving (CNC) β-decay, which is another experimental effort testing the electric charge conservation for nucleons. The current status of COBRA, and the results obtained in measurements of gA quenching, as well as new searches for the CNC β-decay are presented.
