Abstract

We compute the complete conformal trace anomaly coefficients a and c for the full Standard Model, obtaining a = 1991/720 ≈ 2.765 and c = 283/120 ≈ 2.358. These values are approximately 16 and 24 times larger than the electromagnetic contribution alone, respectively. We detail the field counting, highlight the Dirac/Weyl distinction for neutrinos and the color multiplicity for quarks as common sources of error, and discuss implications for Lifshitz cosmology and running vacuum models.
