Avoiding the Goldstone Boson Catastrophe in general renormalisable field theories at two loops
Johannes Braathen, Mark D. Goodsell
We show how the infra-red divergences associated to Goldstone bosons in the minimum condition of the two-loop Landau-gauge effective potential can be avoided in general field theor…
Leading two-loop corrections to the Higgs boson masses in SUSY models with Dirac gauginos
Johannes Braathen, Mark D. Goodsell, Pietro Slavich
We compute the two-loop O(as*at) corrections to the Higgs boson masses in supersymmetric extensions of the Standard Model with Dirac gaugino masses. We rely on the effective-potent…
The Di-Photon Excess in a Perturbative SUSY Model
Karim Benakli, Luc Darmé, Mark D. Goodsell +1
We show that a 750 GeV di-photon excess as reported by the ATLAS and CMS experiments can be reproduced by the Minimal Dirac Gaugino Supersymmetric Standard Model (MDGSSM) without t…
The Higgs mass in the CP violating MSSM, NMSSM, and beyond
Mark D. Goodsell, Florian Staub
We discuss the automatised calculation of the Higgs mass in renormalisable supersymmetric models with complex parameters at the two-loop level. Our setup is based on the public cod…
Precision tools and models to narrow in on the 750 GeV diphoton resonance
Florian Staub, Peter Athron, Lorenzo Basso +8
The hints for a new resonance at 750 GeV from ATLAS and CMS have triggered a significant amount of attention. Since the simplest extensions of the standard model cannot accommodate…
