1-loop, 2-loop and 3-loop numerical counterterms used for calculation of the final 3-loop result and relevant 3-loop parts (on-shell scheme and Feynman gauge, as described in the manuscript https://doi.org/10.48550/arXiv.2603.06571. The numerical input parameters are: MZ = 91.1876 GeVMW = 80.385 GeVMH = 125.1 GeVmt = 173.2 GeV All results are expanded in ε to the orders required for the three-loop calculation. Symbolic notation is according to https://feynarts.de/. Fermionic and bosonic one-loop contributions are denoted by the letters f and b, respectively. The file 1LoopCTRulesNum.m includes results for fermionic and bosonic contributions, where applicable: dMWsq1f, dMWsq1b, dMZsq1f, dMZsq1b, dSW1f, dSW1b, dCW1f, dCW1b, dZAA1b, dZAA1f, dZH1f, dZH1b, dZZZ1f, dZZZ1b, dmH1f, dmH1b, dZAZ1f, dZAZ1b, dZW1f, dZW1b, dTad1f, dZe1b, dZe1f, dZZA1f, dZZA1b, dMf1qcd[3, 3], dMf1b[3, 3], dZfL1[1, 2, 2], dZfR1[1, 2, 2], dZfR1[2, 2, 2]. The file 2LoopCTRulesNum.m includes: dMt2, dTH2, dMHsq2, dMWsq2, dMZsq2, dSW2, dZZZ2, dZZA2, dZAA2, dZe2, dZAZ2, dZW2. 3LoopCTRulesNum.m contains condensed numerical results for three-loop CTs: dMWsq3: O(a^2as) W mass counterterm, Eq.27 dMZsq3: O(a^2as) Z mass counterterm, Eq.28 dZe3: O(a^2as) charge counterterm, Eq.36 dZnL3: O(a^2as) neutrino field renormalization dZeL3: O(a^2as) electron/muon field renormalization dSW3: O(a^2as) weak mixing angle counterterm, Eq.29 dZW2: O(a*as) W boson field renormalization (unphysical, not needed for observable) dG02/dZGp2: O(a*as) Goldstone field renormalization (unphysical, not needed for observable) The results included here may be useful for comparisons with independent calculations and for future work by other groups.
