Neutron-Antineutron Oscillations in Nuclei Revisited


An upper limit on n− n̄ oscillations can be obtained from the stability of matter. This relation has been worked out theoretically and together with data yields τnn̄ > (1 − 2) × 10 sec. A recent publication claims a different relation and finds a nuclear suppression of the n → n̄ oscillations which is two orders of magnitude weaker than the previous… (More)
