Exploring the idea of Broadhurst on the ``sixth root of unity'' we present an ansatz for construction of a basis of transcendental numbers for the epsilon-expansion of single mass scale diagrams with two particle massive cut. As example, several new two- and three-loop master integrals are calculated.

  1. Three-loop corrections to the Fermi decay constant in the $\overline{\rm{MS}}$ scheme

    hep-ph 2025-07 conditional novelty 7.0 of 10

    The leading three-loop corrections to the Fermi decay constant in the pure MS scheme are computed, shifting the Standard Model Higgs VEV down by about 3.5 MeV and cutting residual scale dependence to below 2e-6.

  2. Comparison of the EFT Hybrid and Three-Loop Fixed-Order Calculations of the Lightest MSSM Higgs Boson Mass

    hep-ph 2019-08 conditional novelty 5.0 of 10

    The FeynHiggs NNLL hybrid and the authors' three-loop fixed-order predictions of the MSSM light Higgs mass agree below 10 TeV, and the measured Higgs mass rules out SUSY scales above 12.5 TeV in the heavy-SUSY, no-mix...
