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 …

The existence of colour-octet scalar states, often dubbed sgluons, is predicted in many
extensions of the Standard Model of particle physics, such as supersymmetric realisations …

We consider the effective type-II two-Higgs doublet model originating from Dirac gaugino
models with extended supersymmetry in the gauge sector, which is automatically aligned in …

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 …

A bstract We compute the two-loop\(\mathcal {O}\left ({\alpha} _t {\alpha} _s\right)\)
corrections to the Higgs boson masses in supersymmetric extensions of the Standard Model …

We investigate the conditions for alignment in Dirac Gaugino models with minimal matter
content. This leads to several scenarios, including an aligned Dirac Gaugino NMSSM that …

Supersymmetric models with Dirac instead of Majorana gaugino masses have distinct
phenomenological consequences. In this paper, we investigate the electroweakino sector of …

A bstract Dirac gauginos are a well-motivated extension of the MSSM, leading to interesting
phenomenological consequences. At the LHC, gluino-pair production is enhanced while …

A bstract 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 …

We present a supersymmetric (SUSY) model based on trinification [SU (3)] 3 and family SU
(3) F symmetries embedded into a maximal subgroup of E 8, where the sectors of light Higgs …
