The Washout Criterion With a Bounded Order Parameter: v_c over T_c When the Latent Heat Is Capped

The washout threshold at v_c/T_c = 1 corresponds in this proxy to a strength of only 0.050. A strength of 0.1 requires a jump of 1.41, comfortably beyond the threshold, while a strength of 0.01 corresponds to a jump of 0.45, short of it. The ordering is encouraging for joint scenarios: in this proxy, transitions strong enough to be interesting gravitational-wave sources are automatically strong enough to protect a baryon asymmetry, and the marginal region for baryogenesis sits at strengths below the usual gravitational-wave targets. The latent heats involved remain far below the ceiling cap, so the density bound does not disturb the washout analysis at the electroweak scale. This study is simulated and computed from stated assumptions; it is not a measurement.
