# Anomaly and Cobordism Constraints Beyond Standard Model: Topological Force

@article{Wang2020AnomalyAC, title={Anomaly and Cobordism Constraints Beyond Standard Model: Topological Force}, author={Juven C. Wang}, journal={arXiv: High Energy Physics - Theory}, year={2020} }

Standard lore uses local anomalies to check the kinematic consistency of gauge theories coupled to chiral fermions, e.g. Standard Models (SM). Based on a systematic cobordism classification [1812.11967, 1910.14668], we examine constraints from invertible quantum anomalies (including all perturbative local and nonperturbative global anomalies) for gauge theories. We also clarify the different uses of these anomalies: including (1) anomaly cancellations of dynamical gauge fields, (2) 't Hooft…

Anomaly Indicators for Time-Reversal Symmetric Topological Orders.

This work proposes two quantities, which are called anomaly indicators, that can detect if a time-reversal symmetric topological order is anomalous in this sense, and conjecture that η2, together with a previously known indicator η1, can detect the two known Z_{2} anomalies in the bosonic case, while η_{f} can detecting the Z_{16} anomaly in the fermionic case.
