Title: A New Look at GUT Models Inspired by the $\gamma\gamma$ ResonanceComments: v3: 47 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this article, we look at the recent diphoton peak at run 2. Surprisingly, colored pions are added to minimal composite Higgs to account for the $\gamma\gamma$ resonance. However, the resonance couples not only to $hh$, but also to $ZZ$. Assuming the $\gamma\gamma$ excess is real, we predict that charge 5/3 quarks should be at 300 GeV. We leave the rest for future study.

Title: A New Look at GUT Models Inspired by the $\gamma\gamma$ AnomalyComments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we address the very recent diphoton resonance at run 2 and muon g-2. We study the 750 GeV peak in SU(3)^3. The R symmetry protects the mass of the $\eta$. However, we expect an eta prime above 500 GeV. Our results are similar to work done by Santiago and Hernández.

Title: The 750 GeV Anomaly as a PseudoscalarComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
A few months ago, ATLAS and CMS have measured an anomaly in the second run of the LHC. We study the diphoton excess in $\lambda$SUSY on a torus. Therefore, the shift symmetry protects the mass of the $\phi$, but not the Higgs. Assuming the diphoton excess is real, we predict that light axions should be at 700 GeV. Finally, the phenomenology of E6 is scrutinized and we analyze anomalous dimensions.

Title: On the Diphoton ResonanceComments: 38 pages, typos corrected, 1 tables, minor changesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this letter, we look at the recent diphoton peak at run 2 (at 4.7 sigma). We study the phenomenology of minimal composite Higgs and derive correlations between $hh$ and $Z\gamma$. The flavor symmetry protects the mass of the $S$, but not the Higgs. However, neutral fermions at 700 GeV should be observed soon. We will provide more details in a future paper.

Title: An Unified Explanation for the 750 GeV Anomaly and $B \to D \tau \nu$Authors: I. Wang, A. Sannino, J. Yang, W. Li, B. Jiang, M. Gao, Q. Okada, H. Strassler, N. Dev, Z. SongComments: 4 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen a peak in run 2. We analyze the phenomenology of AdS/CFT and calculate deviations to Higgs couplings. A feature of this model is that it encapsulates all the relevant physics. Unsurprisingly, heavy scalars are required at 500 GeV. Our results are similar to work done by Goudelis and Kats.
