Title: Connecting the Diphoton Excess and the 2 TeV ResonanceComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just shown a peak in the 13 TeV data at 1.5 sigma. Unsurprisingly, the phenomenology of split SUSY models is considered and we compute deviations to Higgs couplings. The $\eta$ is produced in gluon fusion and decays to $\gamma\gamma$. Consequently, vector-like quarks at 800 GeV should be observed soon. More data is likely to confirm this shocking fact.

Title: The Diphoton Anomaly From Fat HiggsComments: 35 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we talk about the very recent diphoton anomaly at run 2. Fortunately, we scrutinize the 750 GeV excess in two Higgs doublet models. Thus, the discrete symmetry protects the mass of the resonance, but not the Higgs. Light axions are required at 500 GeV. We leave the rest for future study.

Title: Interpretations of the Diphoton Resonance in Extensions of Georgi-Machacek ModelsAuthors: P. StrumiaComments: 4 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this article, we address the intriguing diphoton anomaly at run 2. Curiously, we scrutinize the $\gamma\gamma$ peak in folded SUSY. The R symmetry stabilizes the mass of the $S(750)$. Therefore, vector-like quarks at 500 GeV should be observed soon. Finally, we consider the diphoton peak in SU(5) with neutral fermions.

Title: Spin-3/2? Interpretations in Minisplit SUSY ModelsComments: v3: 13 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we address the very recent diphoton resonance at run 2. Quite simply, we analyze the 750 GeV anomaly in composite twin Higgs. The $S$ couples to $Z\gamma$, but not to $b\bar{b}$, decreasing tension with Run 1. However, exotic fermions at 900 GeV should be observed soon. We leave the rest for future study.

Title: Spin-2? Calculating the Mass Spectrum in Gauge-extended ModelsComments: v4: 3 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we address the intriguing diphoton resonance at run 2 (at 2.3 sigma). Curiously, the phenomenology of SO(10) is analyzed and we compute deviations to Higgs couplings. The $\eta$ is produced in the quark antiquark channel and decays to a pair of photons. Remarkably, neutral fermions are required at 700 GeV. More data should reveal the nature of the $\gamma\gamma$ excess.
