Nuclear-atomic state degeneracy in neutrinoless double-electron capture: A unique test for a Majorana-neutrino
D. Frekers
There is a general consensus that detection of a double-beta decay without any neutrino involved would mark physics beyond the Standard Model. This is because in such decay modes l…
Nuclear Input for Core-collapse Models
G. Martinez-Pinedo, M. Liebendoerfer, D. Frekers
We review the nuclear physics input necessary for the study of the collapse of massive stars as precursor to supernova explosions. Recent theoretical advances for the calculation o…
Testing quantum correlations with nuclear probes
S. Hamieh, H. J. Woertche, C. Baeumer +9
We investigated the feasibility of quantum-correlation measurements in nuclear physics experiments. In a first approach, we measured spin correlations of singlet-spin (1S0) proton…
Polarization Correlations of 1S0 Proton Pairs as Tests of Bell and Wigner Inequalities
C. Polachic, C. Rangacharyulu, A. van den Berg +7
In an experiment designed to overcome the loophole of observer dependent reality and satisfying the counterfactuality condition, we measured polarization correlations of 1S0 proton…
