Resonant Protection of Baryon Asymmetry: Bridging the 50 TeV Phase Transition with LHC Heavy-Ion Data

Resonant Protection of Baryon Asymmetry: Bridging the 50 TeV Phase Transition with LHC Heavy-Ion Data

Abstract

We present a robust mechanism for Baryogenesis at the 50 TeV scale that relaxes the requirement for supersonic domain walls. Inspired by recent findings from the ALICE Collaboration [Nature 648 (2025)]—which demonstrate that light nuclei survive the high-temperature hadronic phase via delayed formation from Δ-resonance decays—we propose a holographic dual mechanism. We show that the heavy Top Partners (T'), intrinsic to Composite Higgs models, act as "resonant shields" during the confinement phase transition. By temporarily storing the chiral asymmetry generated at the bubble wall, these states delay the injection of baryon number until the plasma has entered the broken phase. We explicitly derive the Protection Ratio R, demonstrating that due to the hierarchy between the confinement scale (Λ_C) and the resonance mass (M_T'), the shielding length naturally exceeds the wall thickness by a factor of R ~ 10^3 v_w. This effectively bypasses the sphaleron washout danger even in regimes of extreme hydrodynamic friction where the wall is deeply subsonic.
