Neutrino Oscillation Phases Accumulated Through a Bounce
Year: 2026
Type: article
Abstract: On a cosmological bounce background with a single minimum of the scale factor and unit duration, in units set by that duration, the quantities reported here are obtained by direct numerical evolution of the field modes from the contracting branch to the expanding branch. At momentum 1 the phase accumulated through the bounce is 2.055 radians, against 0.020 radians for the fixed-scale-factor comparison over the same interval: the bounce changes the accumulated phase by a substantial factor, it does not merely rescale the clock. The point oscillation probability at that momentum is 0.623, and averaging over the packet reduces it to 0.622. The calculation is performed on a stated model background with stated vacuum conventions, and the code and full-precision output are deposited with the paper. This study is simulated and computed from those assumptions; it is not a measurement.
