  Found the paper, I think: https://arxiv.org/abs/1803.08930 https://arxiv.org/abs/1803.08930 CPT = Charge, Parity, Time Does anyone know why "CPT" is written using a different font?
  • _kulang 5y ago
    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
