【摘要】：Neutron-antineutron ■ oscillations in the deuteron are considered. Specifically, the deuteron lifetime is calculated in terms of the free-space ■ oscillation time ■ based on NN and ■ interactions derived within chiral effective field theory(EFT).This results in ■ s,which is close to the value obtained by chiral effective field theory(EFT). This results in Dover and collaborators more than three decades ago, but disagrees with recent EFT calculations that were performed within the perturbative scheme proposed by Kaplan, Savage, and Wise. Possible reasons for the difference are discussed.
