Title: Interpretations of the 750 GeV Excess in 2HDMsComments: v3: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just shown a resonance in run 2 of the LHC. Unfortunately, the 750 GeV excess is analyzed in technicolor with neutralinos. Actually, the global U(1) symmetry protects the mass of the $X$. Neutral fermions at 900 GeV should be observed soon. More data should reveal the nature of the 750 GeV peak.

Title: A New Look at AdS/CFT Inspired by the Diphoton ExcessComments: v3: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we talk about the intriguing diphoton peak at run 2. Actually, we study the phenomenology of two Higgs doublet models and evaluate decay widths. Moreover, the R symmetry stabilizes the mass of the $X(750)$. We predict a pion below 700 GeV. More data should reveal the nature of the diphoton excess.

Title: The Diphoton Peak: Interpretations in Folded SUSYComments: v4: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this article, we look at the very recent diphoton anomaly at run 2. Surprisingly, vector-like quarks are added to little Higgs to compensate for the diphoton peak. The R symmetry protects the mass of the $\eta$, but not the Higgs. Unfortunately, we expect an eta prime above 600 GeV. Our results are similar to work done by Sannino.

Title: The Diphoton Anomaly From GUT ModelsAuthors: R. RolbieckiComments: 28 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In december, ATLAS and CMS have measured a peak in the 13 TeV data. We scrutinize the phenomenology of little Higgs and predict decay widths. Thus, a drawback of this model is that it is very predictive. Assuming the $\gamma\gamma$ anomaly is real, we predict that conformal dynamics should be at 300 GeV. We will provide more details in a future paper.

Title: Interpretations of the Diphoton Anomaly in Extensions of Flipped SU(5) ModelsAuthors: T. LiComments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just presented an excess in the latest LHC data. New strong dynamics are added to minisplit SUSY models to account for the 750 GeV resonance. The PQ symmetry stabilizes the mass of the $\eta$. Consequently, vector-like fermions are required at 900 GeV. Finally, new gauge interactions are added to $\lambda$SUSY to account for the $\gamma\gamma$ peak.
