“…35 • Other explanations with the (N)MSSM require additional couplings or particles in the spectrum. Examples are solutions in the R-parity violating MSSM, 36,37 or a very low SUSY-breaking scale, where the sgoldstino is identified with Φ 750 , [38][39][40] or within the NMSSM turning nonperturbative at O(10 TeV). 41 …”

The LHC experiments ATLAS and CMS have reported an excess in the diphoton spectrum at \sim 750 GeV. At the same time the motivation for Supersymmetry (SUSY) remains unbowed. Consequently, we review briefly the proposals to explain this excess in SUSY, focusing on "pure" (N)MSSM solutions. We then review in more detail a proposal to realize this excess within the NMSSM. In this particular scenario a Higgs boson with mass around 750 GeV decays to two light pseudo-scalar Higgs bosons. Via mixing with the pion these pseudo-scalars decay into a pair of highly collimated photons, which are identified as one photon, thus resulting in the observed signal.Comment: 10 pages, 2 figures.

“…This possibility has been discussed by [7][8][9][10][11] using an effective description of how the SUSY breaking is mediated to the MSSM sector. In this article, we scrutinise the viability of this proposal when realistic models for the mediation of SUSY breaking are considered.…”

Among the various explanations of the possible 750 GeV diphoton resonance, the possibility of it being an sgoldstino is an attractive one, as it is related to the spontaneous breaking of global supersymmetry. We discuss this possibility in this paper and point out the various theoretical issues associated with it. In particular, we indicate the difficulties of this explanation in realistic models of gauge mediated supersymmetry breaking.

“…However, some of these interpretations are in tension with the non-observation of this resonance in other channels. In supersymmetry, the scalar partner of the goldstino could provide an explanation to the diphoton signal [97,147,167,335]. Other ideas, slightly more exotic, include: a model with a space-time varying electromagnetic coupling constant [135], Gluinonia [337], Squarkonium/Diquarkonium [299], flavons [244], axions in various incarnations [8,24,63,246,274,336], a natural Coleman-Weinberg theory [22,307], radiative neutrino mass models [264,325,327], and string-inspired models [19,132,188,240,254].…”

Precision tools and models to narrow in on the 750 GeV diphoton resonance

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 the observation, many alternatives have been considered to explain the excess. Here we focus on several proposed renormalisable weakly-coupled models and revisit results given in the literature. We point out that physically important subtleties are often missed or neglected. To facilitate the study of the excess we have created a collection of 40 model files, selected from recent literature, for the Mathematica package SARAH. With SARAH one can generate files to perform numerical studies using the tailormade spectrum generators FlexibleSUSY and SPheno. These have been extended to automatically include crucial higher order corrections to the diphoton and digluon decay rates for both CP-even and CP-odd scalars. Additionally, we have extended the UFO and CalcHep interfaces of SARAH, a
