Title: A Common Framework for the Diphoton Anomaly and Natural Inflation
Comments: 14 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just measured an excess in the latest LHC data. The $\gamma\gamma$ peak is analyzed in SU(3)^3 with vector-like fermions. The $\phi$ is produced in inelastic scattering and decays to $\gamma\gamma$. However, a downside of this model is that $b\bar{b}$ and $ZZ$ are predicted to be tiny. Finally, we analyze the phenomenology of the MSSM and evaluate flavor observables.

Title: A New Look at SO(10) Inspired by the $\gamma\gamma$ Resonance
Comments: 3 pages, reference added
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just observed an anomaly in the second run of the LHC. Exotic fermions are added to $\lambda$SUSY to allow for the 750 GeV excess. Quite simply, the conformal symmetry protects the mass of the $X$, but not the Higgs. We expect an eta above 600 GeV. More data is likely to confirm this pretty theorem.

Title: A New Take on the NMSSM Inspired by the $\gamma\gamma$ Peak

In this note, we look at the intriguing diphoton excess at run 2 (at 1.9 sigma). We analyze the diphoton anomaly in split SUSY models with vector-like quarks. In short, the discrete symmetry protects the mass of the $S(750)$, but not the Higgs. Light axions at 300 GeV should be observed soon. Finally, the phenomenology of AdS/CFT is considered and we predict the statistical significance.

Title: A New Take on Minimal Composite Higgs Inspired by the $\gamma\gamma$ Resonance
Comments: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

Less than a year ago, ATLAS and CMS have presented a peak in run 2 of the LHC. Consequently, the phenomenology of singlet-extended models is studied and we calculate cross sections. The $S$ couples not only to $ZZ$, but also to $b\bar{b}$. Assuming the $\gamma\gamma$ excess is real, we predict that new gauge interactions should be at 800 GeV. More data is likely to confirm this unsurprising law.

Title: Interpretations of the Diphoton Excess in Extensions of Seesaw Models

A few months ago, ATLAS and CMS have seen an excess in run 2. Actually, we analyze the $\gamma\gamma$ resonance in gauge-extended models on a D3-brane. A downside of this model is that it is very predictive. Thus, conformal dynamics are required at 300 GeV. Our results are similar to work done by Zhu and Yang.
