Topology of the Standard Model I: Fermions
The Harari-Shupe model for fermions is extended to a topological model which contains an explanation for the observed fact that there are only three generations of fermions. Topological explanations are given for -decay and for proton decay predicted in supersymmetry and string theories. An explanation is given for the observed fact that the three generations of fermions have such similar prope...
متن کاملSpace-geometric Interpretation of Standard Model Fermions
Based on the geometric interpretation of the Dirac equation as an evolution equation on the three-dimensional exterior bundle Λ(R), we propose the bundle (T ⊗Λ⊗Λ)(R) as a geometric interpretation of all standard model fermions. The generalization to curved background requires an ADM decomposition M ∼= M × R and gives the bundle (T ⊗ Λ ⊗ Λ)(M). As a consequence of the geometric character of the ...
متن کاملStandard model effective field theory: integrating out vector-like fermions
We apply the covariant derivative expansion of the Coleman-Weinberg potential to vector-like fermion models, matching the UV theory to the relevant dimension-6 operators in the standard model effective field theory. The γ matrix induced complication in the fermionic covariant derivative expansion is studied in detail, and all the contributing combinations are enumerated. From this analytical re...

متن کامل2 Fermi surface for Standard Model fermions inside horizon
Painlevé-Gullstrand metric of the black hole allows to discuss the fermion zero modes inside the hole. The statistical mechanics of the fermionic microstates can be responsible for the black hole thermo-dynamics. These fermion zero modes also lead to quantization of the horizon area.
