  3. 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. Their mass are million times larger than common ones • 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.

  5. Why Tera-helium is a good Dark Matter gas? • Teraparticles do not have normal W and Z interactions and do not contribute into SM parameters, so they can not be excluded by precision measurements of SM parameters • CP' symmetry of Glashow’s model helps to solve strong CP violation problem in QCD. • Tera-neutrino is unstable, because it gives Dirac see-saw mass to normal neutrino. • UUU as the new form of hadron - bound by ChromoCoulomb forces. It's size is about 1/alpha_QCD m_U about 10^-16 cm and it weakly interacts with hadrons. D.Fargion-Sinister Universe-SUSY-2005- Unification OC218- 19-July-2005

  6. However UUUEE it is reached by multi-body interactions along a tail of more manifest secondary frozen blocks in analogy to He,Li,D. They should be now here polluting the matter. D.Fargion-Sinister Universe-SUSY-2005- Unification OC218- 19-July-2005

  7. Tera Leptons in Glashow’s Sinister Universe • Moreover, in opposition to almost effective pair Tera-Quark U annihilations (like common proton-anti-proton), there is no such an early or late Tera-Lepton pairs suppressions, because: • a) electromagnetic interactions are "weaker" than nuclear ones because their coupling is smaller and mainly because the cross sections is proportional to inverse square Tera-Lepton Mass • b) helium ion 4He++ is able to attract and capture, E-, fixing it into a hybrid tera helium "ion" trap. This takes place during the first few minutes of the Universe D.Fargion-Sinister Universe-SUSY-2005- Unification OC218- 19-July-2005

  8. Why Grave Shadows over theSinister universe? • The helium ion 4He++ capture of E- leads to a pile up of relic (4HeE)+ traces, a lethal compound for any Sinister Universe. • This capture leaves no Tera-Lepton frozen in Ep relic (otherwise an ideal catalyzer to achieve effective late E+E- annihilations possibly saving the model). • The (4HeE)+ Coulomb screening is also avoiding the synthesis of the desired UUUEE hidden dark matter gas. The e(4HeE)+ behave chemically like an anomalous hydrogen isotope. • Also tera-positronium (eE+) relics are over-abundant and they behave like an anomalous hydrogen atom: D.Fargion-Sinister Universe-SUSY-2005- Unification OC218- 19-July-2005

  9. Consequences and Shadows • these hydrogen-like gases do not fit by many orders of magnitude known severe bounds on hydrogen anomalous isotope, making grave shadows over a Sinister Universe. • However a surprising and resolver role for Tera-Pions in UHECR astrophysics has been revealed.

  18. A surprising Role of Tera Pions in UHECR D.Fargion-Sinister Universe-SUSY-2005- Unification OC218- 19-July-2005

  19. Novel Candidate To UHECR • A different and more exciting role may come from the Tera-Hadron UHE secondary of the top-down UHECR source: the birth of neutral Tera-Mesons U-anti-u and u-anti-U. • Contrary to early Universe, where there is enough time and hard dense matter to proceed in the very complex cooking of Tera-Hadrons relics summarized in present article, tera quarks born by UHECR source escape mostly as neutral U-Anti-u and u-Anti-U.

  20. pair production energy loss -resonance pion production energy loss multi-pion production pion production rate The Greisen-Zatsepin-Kuzmin (GZK) cut-off Ultra High Energy Nucleons may produce pions on the 2.75 K BBR  nucleon • sources must be nearby (Local SuperCluster) • Or Neutrino Mediated (Z- Shower Model) Or Lorentz symmetry breaking.

  21. THE UHECR puzzle: Isotropy –Homogeneity- BL Lac correlation D.Fargion-Sinister Universe-SUSY-2005- Unification OC218- 19-July-2005

  22. New Particles and New Interactions Motivated by possible correlations of UHECR with high redshift objects: Gorbunov et al 2002 HIRES 2005 If this is confirmed, one can only think of 3 possibilities: 1.) Neutrino primaries but Standard Model interaction probability in atmosphere is ~10-5. • resonant (Z0) secondary production on massive relic neutrinos: needs extreme parameters and huge neutrino fluxes. • strong interactions above ~1TeV: only moderate neutrino fluxes required. 2.) New heavy neural (SUSY) hadron X0: m(X0) > mNincreases GZK cut-off threshold. but basically ruled out by constraints from accelerator experiments. 3.) New weakly interacting light (keV-MeV) neutral particle electromagnetic coupling small enough to avoid GZK effect; hadronic coupling large enough to allow normal air showers: very tough to do. BUT now Neutral Tera Pion maybe the source D.Fargion-Sinister Universe-SUSY-2005- Unification OC218- 19-July-2005

  23. Tera Pions escaping GZK: • These hybrid pions are very exceptional candidates to UHECR because two surprising abilities. • The first is that they interact hadronically with matter. This may imply a high altitude atmosphere interaction on Earth in agreement with the observed UHECR fluorescence light curve. • The second ability is a very smart interaction with radiation: indeed while the photo-pion production with matter takes place as for all the common nucleons (either proton or neutrons), the threshold in the "center of mass frame" for tera-pions is much higher. D.Fargion-Sinister Universe-SUSY-2005- Unification OC218- 19-July-2005

  24. Are UHECR meta-stable Tera Neutral Pions? • The photo-pion production for neutrons onto the 2.75 K^o BBR begins at Lorentz factor 4 10^{10} and energy E = 4 10^{19} eV while for a corresponding Lorentz factor the Hybrid Tera-Pion threshold energy • E is 1.4 10^{23} eV, is above three order of magnitude higher simply because of the huge Tera-pion mass respect nucleon one. • This imply that for Tera-Pion there is a GZK cut off much above common {Greisen}{Zatsepin, Kuzmin} energies E= 4 10^{19} eV making this rare UHE tera-pion an ideal candidate able to travel along the whole Universe without deflection of Galactic or Extra-galactic magnetic fields or much energy losses, overcoming the otherwise controversial absence of a GZK cut-off. These Tera-pions are among the best candidate to solve recent UHECR correlated events with far BL-Lac sources {Gorbunov et al 2005}{HiRes,ICRC 2005}. D.Fargion-Sinister Universe-SUSY-2005- Unification OC218- 19-July-2005

  25. Conclusions: • No Sinister Dark Matter Cosmology because the Tera-Lepton Shadows hanging over the model. But possible role for meta-stable Tera-pions Uu and uU originated in Jets by BL Lac or in TD evaporation, able to travel undeflected and with no energy loss behaving as nuclear matter.
