Title: On the $\gamma\gamma$ ResonanceAuthors: O. GoudelisComments: v3: 11 pages, added refs, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just presented an anomaly in the second run of the LHC at 2.4 sigma. Curiously, we study the phenomenology of Georgi-Machacek models and evaluate 4-body decays. Fortunately, the resonance couples not only to $ZZ$, but also to $b\bar{b}$. We predict a color sextet below 400 GeV. Our results are similar to work done by Yu and Franceschini.

Title: A New Look at GUT Models Inspired by the $\gamma\gamma$ AnomalyComments: v4: 45 pages, added refs, JHEP3, JHEP3, based on a talk given on Georgi's 10th birthdaySubjects: High Energy Physics - Phenomenology (hep-ph)
A few months ago, ATLAS and CMS have observed an anomaly in the latest LHC data. We study the phenomenology of the MSSM and compute decay widths. The $S$ is produced in vector boson fusion and decays to two photons. Curiously, the 750 GeV resonance implies charge 1/5 quarks around 600 GeV. We leave the rest for future study.

Title: Interpretations of the Diphoton Resonance in Pati-Salam ModelsAuthors: L. LangackerComments: 4 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we talk about the very recent diphoton excess at run 2 and the galactic center excess. The phenomenology of minisplit SUSY models is studied and we evaluate the statistical significance. The resonance is produced in elastic scattering and decays to two photons. Remarkably, assuming the 750 GeV anomaly is real, we predict that exotic fermions should be at 300 GeV. We leave the rest for future study.

Title: Interpretations of the 750 GeV Peak in GUT ModelsAuthors: E. TerningComments: v2: 27 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we look at the recent diphoton anomaly at run 2 (at 4.0 sigma). We scrutinize the 750 GeV peak in $\lambda$SUSY with vector-like quarks. The R symmetry protects the mass of the $X(750)$. Unsurprisingly, we expect a pion above 400 GeV. More data should reveal the nature of the 750 GeV excess.

Title: A Common Framework for the 750 GeV Peak and $B \to D \tau \nu$Comments: v3: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just released a peak in the 13 TeV data at 3.4 sigma. Surprisingly, we analyze the diphoton peak in gauge-extended models on AdS_5. Quite simply, the R symmetry stabilizes the mass of the $S(750)$. Neutralinos are required at 700 GeV. More data should reveal the nature of the $\gamma\gamma$ resonance.
