Tera-Leptons Shadows over Sinister Universe
D. Fargion, M. Khlopov

TL;DR
This paper explores the implications of Sinister Heavy Fermions in a specific particle physics model, highlighting potential conflicts with observational bounds due to relic particles and proposing a role for Tera-Pions in ultra-high-energy cosmic rays.
Contribution
It introduces the impact of relic tera-leptons and their interactions in the Sinister model, revealing conflicts with experimental bounds and suggesting a new astrophysical role for Tera-Pions.
Findings
Relic (4HeE)+ traces could pollute matter, conflicting with observations.
Over-abundance of tera-positronium relics challenges the model.
Tera-Pions may play a significant role in ultra-high-energy cosmic rays.
Abstract
The role of Sinister Heavy Fermions in recent Glashow's SU(3)*SU(2)*SU(2)'*U(1) model is to offer in a unique frame relic Helium-like products (an ingenious candidate to the dark matter puzzle), a solution to the See-Saw mechanism for light neutrino masses as well as to strong CP violation problem in QCD. The Sinister model requires a three additional families of leptons and quarks, but only the lightest of them Heavy U-quark and E-"electron" are stable. Final neutral Helium-like UUUEE state is an ideal evanescent dark-matter candidate. However it is reached by multi-body interactions along a tail of more manifest secondary frozen blocks. They should be now here polluting the surrounding matter. Moreover, in opposition to effective pair quark annihilations, there is no such an early or late tera-lepton pairs suppressions, because:a) electromagnetic interactions are "weaker" than nuclear…
