Possible Standard Model solution for Baryon Asymmetry

TL;DR

This paper proposes a novel explanation for baryon asymmetry based on Higgs-bound top quark states, suggesting long-lived antibaryons could evolve into antimatter black holes in the early universe.

Contribution

It introduces a new Standard Model-based mechanism involving Higgs-bound top quark states to account for baryon asymmetry without requiring new physics.

Findings

Long-lived 2-antitop baryons could form antimatter black holes.

The proposed mechanism aligns with observed matter-antimatter imbalance.

Higgs-exchange binding energy plays a key role in baryon mass and stability.

Abstract

If the discovered Higgs boson with $m_H$=125 GeV is interpreted as a $t\bar{t}$-boson where the $t$-quarks are bound by Higgs-exchange with binding energy 220 GeV, then the $2t$-baryons should have approximately the same mass as the Higgs-boson. As $m_H<m_t$, the life time of $2t$-baryons must be much bigger then the life time of $1t$-baryons. If in the primordial Universe the number of $2\bar{t}$-antibaryons was bigger than the number of $2t$-baryons, then the excess should be compensated by nucleons. The relatively long living heavy $2\bar{t}$-antibaryons could in primordial Universe fast evolve to antimatter black halls and disappear in the world of matter under the Schwarzschild spheres.
