# Nonperturbative definition of the standard models

@article{Wang2020NonperturbativeDO, title={Nonperturbative definition of the standard models}, author={Juven C. Wang and Xiao-Gang Wen}, journal={Physical Review Research}, year={2020} }

The Standard Models contain chiral fermions coupled to gauge theories. It has been a long-standing problem to give such gauged chiral fermion theories a quantum non-perturbative definition. By classification of quantum anomalies and symmetric invertible topological orders via a mathematical cobordism theorem for differentiable and triangulable manifolds, and the existence of symmetric gapped boundary for the trivial symmetric invertible topological orders, we propose that Spin(10) chiral…
