Title: An Unified Explanation for the Diphoton Excess and the Strong CP ProblemAuthors: Z. Goudelis, V. Patra, B. Cline, Z. Yagyu, U. Yagyu, I. Delaunay, C. Torre, T. Sadhukhan, N. Zhang, N. OmuraComments: v2: 4 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we discuss the recent diphoton peak at run 2 (at 3.4 sigma). In short, we analyze the phenomenology of flipped SU(5) models and analyze flavor observables. The $X(750)$ is produced in elastic scattering and decays to a pair of photons. Assuming the diphoton peak is real, we predict that new gauge interactions should be at 700 GeV. We leave the rest for future study.

Title: Spin-3/2? Calculating the Diphoton Rate in the NMSSMComments: v2: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this article, we discuss the very recent diphoton resonance at run 2. We analyze the 750 GeV peak in split SUSY models on a D3-brane. The shift symmetry protects the mass of the $X$, but not the Higgs. Curiously, the resonance couples not only to $WW$, but also to $WW$. More data should reveal the nature of the diphoton anomaly.

Title: The Diphoton Anomaly as a Pseudo Nambu Goldstone BosonComments: 34 pages, BibTeXSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported a resonance in the latest LHC data. We study the $\gamma\gamma$ anomaly in $\lambda$SUSY on a lattice. However, the discrete symmetry protects the mass of the $S(750)$. Assuming the 750 GeV anomaly is real, we predict that vector-like fermions should be at 400 GeV. More data should reveal the nature of the 750 GeV peak.

Title: The $\gamma\gamma$ Excess as a PseudoscalarAuthors: J. NomuraComments: v3: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this paper, we discuss the intriguing diphoton peak at run 2. Even though the diphoton peak could be a statistical fluctuation, we consider the phenomenology of E6 and compute the full mass spectrum. The shift symmetry protects the mass of the $X(750)$, but not the Higgs. However, the $\gamma\gamma$ peak implies conformal dynamics around 300 GeV. More data is likely to confirm this elaborate principle.

Title: Explaining the $\gamma\gamma$ Anomaly and the Strong CP ProblemComments: 43 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen an anomaly in the latest LHC data. The phenomenology of folded SUSY is scrutinized and we derive cross sections. The conformal symmetry protects the mass of the $\phi$, but not the Higgs. In short, we predict a color sextet below 900 GeV. Our results are similar to work done by Kuo.
