Title: On the Diphoton AnomalyComments: v2: updated figure 1, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this article, we discuss the very recent diphoton excess at run 2 and the strong CP problem. Quite simply, the phenomenology of SU(5) is considered and we analyze decay widths. The R symmetry protects the mass of the $\eta$, but not the Higgs. Therefore, charge 2/5 quarks are required at 800 GeV. We will provide more details in a future paper.

Title: A New Take on Fat Higgs Inspired by the 750 GeV ExcessComments: 28 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just shown a peak in run 2. We consider the diphoton anomaly in composite twin Higgs with charge 5/3 quarks. In short, the $\phi$ is produced in vector boson fusion and decays to a pair of photons. We predict a heavy pion below 500 GeV. We will provide more details in a future paper.

Title: Interpretations of the 750 GeV Excess in Extensions of Twin HiggsAuthors: K. ChaoComments: v2: updated figure 4, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just reported an anomaly in run 2 of the LHC at 4.3 sigma. The $\gamma\gamma$ anomaly is studied in SU(5) with new strong dynamics. The $\eta$ couples not only to $b\bar{b}$, but also to $Z\gamma$. Quite simply, conformal dynamics at 600 GeV should be observed soon. Our results are similar to work done by Su.

Title: Relating the $\gamma\gamma$ Excess and the Strong CP ProblemComments: v2: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
Just recently, ATLAS and CMS have seen a peak in the second run of the LHC. The diphoton peak is analyzed in technicolor with vector-like quarks. The R symmetry protects the mass of the $X$, but not the Higgs. Unsurprisingly, we expect an eta above 600 GeV. We leave the rest for future study.

Title: Interpretations of the 750 GeV Peak in Extensions of GUT ModelsAuthors: L. RenComments: v3: 2 pages, typos corrected, 2 tablesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this letter, we look at the recent diphoton anomaly at run 2 (at 1.3 sigma). We scrutinize the diphoton anomaly in $\lambda$SUSY with colored pions. Remarkably, the resonance couples not only to $ZZ$, but also to $ZZ$. We predict an eta below 600 GeV. Our results are similar to work done by Sengupta and Redi.
