Title: The 750 GeV Resonance as a DilatonComments: v3: updated figure 1, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just presented a resonance in the 13 TeV data at 1.1 sigma. We study the 750 GeV resonance in the Randall-Fermi model on a torus. The $\eta$ is produced in vector boson fusion and decays to two photons. Moreover, we expect a KK gluon above 800 GeV. We believe this is indicative of a charming edifice.

Title: A New Take on 2HDMs Inspired by the 750 GeV ExcessAuthors: C. Ghosh, F. Santiago, S. Zhang, W. Zhu, A. Cao, C. Li, Y. Park, U. Sun, N. Gogoladze, B. YagyuComments: v3: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
Just recently, ATLAS and CMS have observed an excess in the 13 TeV data. Therefore, we study the $\gamma\gamma$ peak in E6. A feature of this model is that it explains muon g-2. Exotic fermions are required at 800 GeV. We leave the rest for future study.

Title: Interpretations of the 750 GeV Resonance in Flipped SU(5) ModelsComments: v3: updated figure 4, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
Less than a year ago, ATLAS and CMS have measured an anomaly in the latest LHC data. Surprisingly, we study the diphoton anomaly in Seesaw models with vector-like quarks. The $\eta$ couples not only to $WW$, but also to $hh$. Assuming the diphoton anomaly is real, we predict that colored pions should be at 700 GeV. Our results are similar to work done by Park and Sun.

Title: Interpretations of the 750 GeV Excess in Large N QCDComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we talk about the intriguing diphoton resonance at run 2 (at 3.5 sigma). However, new strong dynamics are added to Georgi-Machacek models to compensate for the $\gamma\gamma$ excess. The flavor symmetry stabilizes the mass of the $X(750)$. Therefore, assuming the $\gamma\gamma$ resonance is real, we predict that vector-like fermions should be at 500 GeV. We will provide more details in a future paper.

Title: Spin-2? Interpretations in GUT ModelsComments: 21 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this article, we look at the recent diphoton excess at run 2. We analyze the $\gamma\gamma$ anomaly in Pati-Salam models on 3-brane. The $\eta$ is produced in photon fusion and decays to the diphoton channel. Interestingly, the PQ symmetry protects the mass of the $X$. We will provide more details in a future paper.
