Reheating After Percolation When the Total Density Is Bounded: The Temperature the Plasma Actually Reaches

For a transition percolating at 90 GeV with strength unity, reheating reaches 107.0 GeV, a rise of 18.9 percent: noticeable, and large enough to matter for a sphaleron rate evaluated at the wrong temperature, but far from dramatic. The extreme case on the grid, percolation at 20 GeV after supercooling to a strength of 100, reheats to 63.4 GeV, recovering much of the temperature lost during supercooling yet remaining below the original critical temperature region. No case approaches the ceiling temperature of 1.05e+09 GeV; reaching it by reheating would require a strength of order the ceiling-to-radiation ratio at the percolation temperature, which the latent-heat envelope already excludes except for percolation temperatures themselves near the ceiling. This study is simulated and computed from stated assumptions; it is not a measurement.
