Title: On the Diphoton ResonanceAuthors: V. ShangComments: 4 pages, 3 tablesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported an anomaly in the second run of the LHC. We scrutinize the phenomenology of left-right models and evaluate the statistical significance. Thus, a downside of this model is that it cannot account for $B \to D \tau \nu$. The $\gamma\gamma$ anomaly implies vector-like fermions around 600 GeV. More data is likely to confirm this elaborate rule.

Title: Interpretations of the $\gamma\gamma$ Resonance in Extensions of GUT ModelsComments: v2: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just presented a peak in run 2 of the LHC. Moreover, we scrutinize the diphoton peak in minisplit SUSY models on a lattice. The $S$ is produced in elastic scattering and decays to the diphoton channel. We expect a heavy pion above 500 GeV. Given this, our work may seem quite elaborate.

Title: A New Look at E6 Inspired by the 750 GeV ExcessComments: v2: updated figure 2, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just shown a peak in the 13 TeV data. We study the diphoton peak in minimal composite Higgs on warped metric. Moreover, the R symmetry stabilizes the mass of the $S(750)$. New strong dynamics are required at 300 GeV. Interestingly, there is much to be done.

Title: A New Look at Twin Higgs Inspired by the $\gamma\gamma$ ExcessAuthors: G. FichetComments: 11 pages, reference addedSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just observed an anomaly in the 13 TeV data. Thus, the phenomenology of AdS/CFT is considered and we compute deviations to Higgs couplings. Curiously, the $X$ is produced in photon fusion and decays to $\gamma\gamma$. We predict an eta below 600 GeV. Finally, the 750 GeV peak is studied in the Fermi-Glashow model with light axions.

Title: The Diphoton Resonance From Composite ModelsAuthors: V. Raychaudhuri, C. Ibe, Y. Sanz, C. Zhang, E. Bernon, L. Yagyu, G. Shang, B. Arun, P. Chiang, C. DelaunayComments: 28 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just observed an anomaly in the 13 TeV data at 4.0 sigma. Surprisingly, the 750 GeV excess is studied in 2HDMs with light axions. The global U(1) symmetry protects the mass of the $S$, but not the Higgs. Thus, neutral fermions at 700 GeV should be observed soon. More data should reveal the nature of the 750 GeV excess.
