Title: A New Look at Large N QCD Inspired by the 750 GeV ResonanceAuthors: J. YuComments: v3: added refs, 3 tablesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen an anomaly in run 2 of the LHC at 4.7 sigma. We scrutinize the phenomenology of the NMSSM and compute deviations to Higgs couplings. The $X$ is produced in the quark antiquark channel and decays to a pair of photons. In short, a feature of this model is that $WW$ and $hh$ are predicted to be sizable. More data should reveal the nature of the 750 GeV peak.

Title: A New Take on Large N QCD Inspired by the $\gamma\gamma$ ExcessComments: v3: updated figure 2, conclusions unchanged, pdflatexSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this article, we talk about the intriguing diphoton anomaly at run 2. Quite simply, the phenomenology of AdS/CFT is studied and we evaluate deviations to Higgs couplings. The $X$ couples to $Z\gamma$, but not to $t\bar{t}$, worsening tension with Run 1. Assuming the 750 GeV peak is real, we predict that conformal dynamics should be at 300 GeV. We believe this is indicative of a sophisticated edifice.

Title: The 750 GeV Anomaly as a PionAuthors: U. GoudelisComments: 40 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen an excess in the latest LHC data at 2.9 sigma. Fortunately, the phenomenology of split SUSY models is considered and we derive decay widths. The $\phi$ is produced in inelastic scattering and decays to a pair of photons. New gauge interactions are required at 400 GeV. Our results are similar to work done by Kobakhidze and Khoze.

Title: The 750 GeV Excess as a DilatonAuthors: T. StrasslerComments: 4 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just shown a peak in the second run of the LHC. The 750 GeV resonance is scrutinized in two Higgs doublet models with vector-like quarks. Moreover, the R symmetry stabilizes the mass of the $X$. We predict a dilaton below 500 GeV. Our results are similar to work done by Hamada and Zhang.

Title: A New Take on Gauge-extended Models Inspired by the $\gamma\gamma$ PeakAuthors: E. LangackerComments: v3: 45 pages, no figures, no figuresSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this letter, we talk about the very recent diphoton anomaly at run 2 and the doublet-triplet splitting problem. We study the phenomenology of E6 and analyze decay widths. Fortunately, the PQ symmetry protects the mass of the resonance, but not the Higgs. Exotic fermions are required at 700 GeV. We will provide more details in a future paper.
