there is another way to look at the class of gauge theories from the ungauged theories (say like U(1) gauge theories or SU(2) Yang-Mills twisted by SPTs) https://arxiv.org/abs/1904.00994 e.g. Sec 3 and Appendix A

(1) The first way by topological terms (SPTs): SU(2) Yang-Mills twisted by SPTs) https://arxiv.org/abs/1904.00994 e.g. Sec 3 and Appendix A
(2) Second way I look at the problem is in Sec 2

Lorentz sym fractionalization.
