We extend the framework of analyzing the 2HDM in its orbit space to study the one-loop effective potential before and after electroweak symmetry breaking. In this framework, we present a comprehensive analysis of global symmetries of the one-loop thermal effective potential in the 2HDM, demonstrating when the global symmetries of the tree-level 2HDM potential are broken by loop contributions. By introducing light-cone coordinates and generalizing the bilinear notation around the vacuum, we present a geometric view of the scalar mass matrix and on-shell renormalization conditions.

  1. The Two-Higgs Doublet Model beyond tree-level: A gauge-invariant formalism

    hep-ph 2025-05 conditional novelty 6.0 of 10

    The bilinear formalism of the two-Higgs-doublet model is extended to one-loop order, yielding gauge-invariant expressions for the quantum-corrected scalar masses and vacuum shift.

  2. Goofy is the new Normal

    hep-ph 2025-04 conditional novelty 5.0 of 10

    Goofy transformations define new renormalization-group-stable parameter relations in the two-Higgs-doublet model that are not ordinary symmetries.
