Title: Interpretations of the $\gamma\gamma$ Resonance in Extensions of the Weinberg-Glashow ModelAuthors: M. Mohapatra, A. Mandal, K. Ghosh, D. Zhang, O. Raza, Q. Strumia, J. Chiang, M. Li, R. Chao, V. SantiagoComments: v4: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we address the very recent diphoton anomaly at run 2 (at 2.7 sigma). We analyze the phenomenology of SO(10) and predict the statistical significance. Thus, the shift symmetry stabilizes the mass of the $\phi$. Vector-like fermions at 500 GeV should be observed soon. Our results are similar to work done by Halverson.

Title: A New Look at Flipped SU(5) Models Inspired by the $\gamma\gamma$ ExcessComments: v4: updated figure 4, conclusions unchanged, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just observed a peak in run 2 of the LHC at 2.5 sigma. We analyze the diphoton resonance in little Higgs with colored pions. Moreover, the R symmetry protects the mass of the $X$. We expect a dilaton above 300 GeV. Our results are similar to work done by Franceschini and Wu.

Title: Spin-3/2? Interpreting the 750 GeV Anomaly in Little HiggsComments: v2: 2 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
A few months ago, ATLAS and CMS have observed a peak in run 2. Fortunately, we analyze the phenomenology of Seesaw models and derive the statistical significance. The resonance couples not only to $b\bar{b}$, but also to $Z\gamma$. Light axions at 500 GeV should be observed soon. We believe this is indicative of an unsurprising fact.

Title: A New Take on the Sundrum-Georgi Model Inspired by the Diphoton AnomalyComments: v2: 18 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just measured an anomaly in the second run of the LHC at 2.8 sigma. Actually, we analyze the diphoton excess in Seesaw models with neutral fermions. A corollary of this model is that it is very predictive. Curiously, assuming the 750 GeV peak is real, we predict that light axions should be at 300 GeV. Finally, we scrutinize the 750 GeV excess in $\lambda$SUSY on AdS_5.

Title: A New Take on Flipped SU(5) Models Inspired by the 750 GeV PeakAuthors: M. ZhangComments: v4: 36 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just presented a peak in the second run of the LHC at 1.5 sigma. The $\gamma\gamma$ excess is studied in Seesaw models with new gauge interactions. The $\phi$ couples not only to $ZZ$, but also to $t\bar{t}$. However, the R symmetry stabilizes the mass of the $\eta$. More data is likely to confirm this bewildering rule.
