Fermion Families and Pontryagin Class: Topological Field Theory via Colour Symmetry Extension

Zheyan Wan, Juven Wang, Shing-Tung Yau

Family puzzle asks why the Standard Model (SM) features exactly 3 families of quarks and leptons. Motivated by topological constraints, we study 4d fermionic anomalies with discret…
