Gravitational waves (GWs) were recently detected for the first time. This revolutionary
discovery opens a new way of learning about particle physics through GWs from first-order …

Predictions for the Higgs masses are a distinctive feature of supersymmetric extensions of
the Standard Model, where they play a crucial role in constraining the parameter space. The …

A bstract We revisit the scalar potential in the Litim-Sannino model. We compute for the first
time the full quantum corrections to the classical potential and show that they significantly …

We compute the dominant two-loop corrections to the Higgs trilinear coupling λ _ hhh λ hhh
and to the Higgs quartic coupling λ _ hhhh λ hhhh in models with extended Higgs sectors …

The calculation of the Higgs mass in general renormalisable field theories has been
plagued by the so-called “Goldstone Boson Catastrophe,” where light (would-be) Goldstone …

We discuss the systematic evaluation of three-loop vacuum integrals with arbitrary masses.
Using integration by parts, the general integral of this type can be reduced algebraically to a …

We present an implementation and numerical study of the Standard Model couplings,
masses, and vacuum expectation value (VEV), using the pure MS¯ renormalization scheme …

I present the effective potential at three-loop order for a general renormalizable theory, using
the MS¯ renormalization scheme and Landau gauge fixing. As applications and illustrative …

A bstract We present our computation of the\(\mathcal {O}\)((α t+ α λ+ α κ) 2) two-loop
corrections to the Higgs boson masses of the CP-violating Next-to-Minimal Supersymmetric …

We calculate the complete tadpoles and self-energies at the two-loop order for scalars in
general renormalisable theories, a crucial component for calculating two-loop electroweak …
