Abstract: | The mass neutrino interference phase in a global monopole space time along the null trajectory and the geodesic is studied,
and we find that the conserved energy changes a factor when a particle travels along the geodesic, if compared with the energy
in the space time without the global monopole. The oscillation phase is increased by a factor due to the correction of the
global monopole, comparing with the case in Schwarzschild space time. We obtain that the type-I phase along both the null
and geodesic has a difference of a factor of 1−8π
η
2, and that the phase along the geodesic is the double of that along the null. |
