Title: The 750 GeV Anomaly as an Eta PrimeAuthors: J. YanagidaComments: v2: 25 pages, added refs, BibTeXSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we talk about the very recent diphoton excess at run 2. Therefore, colored pions are added to 2HDMs to account for the 750 GeV resonance. However, the conformal symmetry protects the mass of the $S$, but not the Higgs. Vector-like fermions at 600 GeV should be observed soon. We leave the rest for future study.

Title: On the Diphoton ExcessComments: 18 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we talk about the very recent diphoton resonance at run 2 and $h \to \mu \tau$. Fortunately, even though the diphoton anomaly could be a statistical fluctuation, light axions are added to SU(3)^3 to allow for the $\gamma\gamma$ resonance. Quite simply, the $S$ couples not only to $b\bar{b}$, but also to $WW$. Assuming the diphoton excess is real, we predict that vector-like fermions should be at 300 GeV. More data is likely to confirm this important edifice.

Title: Interpretations of the $\gamma\gamma$ Peak in Extensions of TechnicolorComments: 4 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just measured a peak in run 2 of the LHC. We study the phenomenology of AdS/CFT and compute cross sections. Remarkably, the resonance couples not only to $Z\gamma$, but also to $hh$. The $\gamma\gamma$ anomaly implies new strong dynamics around 600 GeV. We leave the rest for future study.

Title: An Unified Explanation for the Diphoton Excess and $h \to \mu \tau$Comments: 15 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we talk about the intriguing diphoton excess at run 2 (at 1.1 sigma). We scrutinize the phenomenology of GUT models and calculate deviations to Higgs couplings. Therefore, the PQ symmetry protects the mass of the $S(750)$. Conformal dynamics at 400 GeV should be observed soon. Finally, the phenomenology of AdS/CFT is scrutinized and we evaluate the statistical significance.

Title: A New Take on Georgi-Machacek Models Inspired by the $\gamma\gamma$ ResonanceAuthors: T. YagyuComments: 19 pages, pdflatex, BibTeXSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
Recently, ATLAS and CMS have measured a peak in the latest LHC data. We consider the diphoton anomaly in E6 on a lattice. Therefore, a feature of this model is that it cannot account for the core-cusp problem. We predict a pion below 500 GeV. We believe this is indicative of an arresting framework.
