Title: On the Diphoton PeakComments: 11 pages, pdflatexSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this paper, we look at the intriguing diphoton anomaly at run 2. The 750 GeV anomaly is analyzed in GUT models with charge 2/5 quarks. The $X(750)$ couples to $WW$, but not to $WW$, decreasing tension with Run 1. Surprisingly, the global U(1) symmetry protects the mass of the resonance. We believe this is indicative of an arresting truth.

Title: A New Take on Left-right Models Inspired by the $\gamma\gamma$ ResonanceComments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just reported an excess in the latest LHC data. Unsurprisingly, we analyze the phenomenology of large N QCD and evaluate deviations to Higgs couplings. In short, the conformal symmetry protects the mass of the $S(750)$. We expect an axino above 800 GeV. More data should reveal the nature of the $\gamma\gamma$ excess.

Title: On the $\gamma\gamma$ AnomalyComments: 19 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we look at the intriguing diphoton excess at run 2 (at 4.9 sigma). We consider the 750 GeV resonance in singlet-extended models with vector-like fermions. The flavor symmetry stabilizes the mass of the $S(750)$. Curiously, we predict a color sextet below 500 GeV. More data should reveal the nature of the 750 GeV resonance.

Title: The $\gamma\gamma$ Peak: Calculating the NLO Cross Section in GUT ModelsComments: v3: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have observed an anomaly in the 13 TeV data. We consider the phenomenology of large N QCD and compute the statistical significance. The global U(1) symmetry protects the mass of the $X$. Quite simply, the $X(750)$ couples not only to $hh$, but also to $WW$. Our results are similar to work done by Zhang and Sanz.

Title: On the Diphoton PeakAuthors: Y. UrbanoComments: v4: 4 pages, 48 figuresSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just shown an excess in run 2 of the LHC. Quite simply, we consider the phenomenology of folded SUSY and predict branching ratios. Thus, the discrete symmetry protects the mass of the resonance. Assuming the diphoton anomaly is real, we predict that light axions should be at 300 GeV. Our results are similar to work done by Tesi.
