The Axion Minicluster Mass Scale Set by the Horizon at Oscillation, Evaluated in a Bounced History
Year: 2026
Type: article
Abstract: At an oscillation temperature of 1 GeV the Hubble rate is 2.92e+05 per second, the total mass within the horizon is 3.47e-01 solar masses, and the scaled minicluster mass is 1.00e-12 solar masses. If oscillation is delayed to 0.15 GeV the minicluster mass rises to 2.96e-10 solar masses, following the inverse-cube scaling. The bound density of 9.72e+54 g per cubic centimetre enters none of these figures, because the horizon at GeV temperatures is a property of the GeV plasma alone. The minicluster mass scale is 1.00e-12 solar masses for oscillation at 1 GeV, rising as the inverse cube of the oscillation temperature, and it is identical in the bounced history because the relevant horizon is set at the oscillation epoch itself. This study is computed from stated assumptions and published comparison values; it is not a measurement.
