Found the paper, I think: https://arxiv.org/abs/1803.08930

CPT = Charge, Parity, Time

Does anyone know why "CPT" is written using a different font?

Yea it’s a math font, “CPT” can be thought of as a mathematical expression of sorts. Other symmetries like CT, CP, don’t hold

C,P,T are also operators that act on states | ψ>.
