Key quantitative content: temperature rises with collision energy and saturates at T ≈ 165 MeV; mu_B falls with sqrt(s_NN) because the same net baryon number spreads over a wider rapidity range (Fig. 4); thermal-model fits extrapolate to LHC (sqrt(s_NN) = 5.5 TeV) with similar T and lower mu_B. The penalty factor per added nucleon, PF ≈ exp(-(m_N - mu_B)/T) (Appendix eq. 1), is measured to describe light-nucleus production at AGS, SPS and RHIC; coalescence-model estimates agree with it (A=20 suppression 1e-53 to 1e-46 vs thermal 1e-49). The Cu+Cu result and the measured velocity distributions are what validate the two assumptions of the earlier Moon-survival argument.
