Parity of the neutron consistent with neutron-antineutron oscillations

In the analysis of neutron-antineutron oscillations, it has recently been argued in the literature that the use of the i gamma(0) parity n(p)(t, -(x) over right arrow) = i gamma(0)n(t, -(x) over right arrow), which is consistent with the Majorana condition, is mandatory and that the ordinary parity transformation of the neutron field n(p)(t, -(x) over right arrow) = i gamma(0)n(t, -(x) over right arrow) has difficulties. We show that a careful treatment of the ordinary parity transformation of the neutron works in the analysis of neutron-antineutron oscillations. Technically, CP symmetry in a mass diagonalization procedure is important and the two parity transformations i gamma(0)-parity and gamma(0)-parity are compensated for by the PauliGursey transformation. Our analysis shows that either choice of parity gives the correct results for neutronantineutron oscillations if carefully treated.
